Aww you?re welcome!
I saw that you posted another dream and I hope to get to that within my winter break.
In general, a house represents your soul and self, with particular rooms indicating a certain aspect of yourself. Since you were in your uncle?s house, it could represent the part of your self and soul concerning your family heritage and trait, new ideas, or awareness. First, you began in the game room with your sister. Family in general has to do with aspects you associate with your family members. Since there are a lot of family members and friends here, definitely consider aspects you like and admire about them that you would want to incorporate in yourself. Sisters are also there to either draw your attention to your family role or to serve as a pun on a nun and represent spiritual issues. For now, I go with family since there seems to be a lot of family related symbols, but I thought it would be best to keep the other meaning in mind as well. The room you are in represents a part of yourself and your hidden parts of your mind and personality. The game room probably indicates a part of yourself that desires a break from daily life and relaxation. However, it may also represent your competitive spirit. Watching television represents your mind?s thoughts and how you are receiving, integrating, and expressing your ideas. Things that you watch on television are things that are in your mind. You then realized that there was a party, which suggests needing to get out more and enjoy yourself. Your mother represents the nurturing part of yourself, shelter, comfort, life, guidance, and protection. Also consider your relationship with your mother. Some people might have problems being free from their parents and the symbol also represents seeking individuality and development. She seemed to be angry at you, representing your own frustrations and disappointments on yourself that you might have projected onto others or repressed. Expressions of anger are usually carried over from waking life. This first portion of the dream seems to be telling you to look at aspects of your family. Perhaps it is suggesting you take a break and spend time with them or at the very least, go and enjoy yourself. Maybe this lack of a break has been weighing on your mind and making you frustrated.
Next you see fictional characters from Attack on Titan. It may come as a surprise to you that I haven?t watched it, but I have heard of it and know at least some of the basics. Definitely consider the themes of Attack on Titan in regards to the next part. You would probably know how to interpret this portion best keeping that in mind, but I will try to offer my two cents here with the bits that I searched up for Attack on Titan. In general, fictional characters imply trying to escape from reality or archetypal symbols depending on the character. You need to consider the qualities of the character and how you can incorporate or acknowledge those aspects. Armin?s qualities seems to be: loyalty, selflessness, kind-heartedness, being concerned about the safety of friends, and having a level-head. Marco (if it was Marco) values others over own interests, is respected greatly, is a good judge of character, and is one who preserves order. Consider which of these aspects are being called into question in the dream and which do you have or want to incorporate within yourself. Tunnels might refer to a need for security and nurturance, but since you actually go though it, the symbols probably suggests exploring parts of your subconscious. You are opening yourself to awareness. There is a negative aspect of tunnels because of the phrase ?tunnel vision? or being close-minded, but I think it is positive because it lead to the outside which is freedom, openness, and opportunities. It was in the wall which should have represented barriers to progress. However, because there was a tunnel in it, you seemed to have opened up your mind and removed the barrier. I would also consider the significance of walls from Attack on Titan, especially how Armin seems to have wanted to learn about the outside of the walls (I hope I got this correct). You bumped your head but kept going on and hid it. Injuries suggests needing to work on healing old wounds and hurts, stopping and slowing down. Since you hurt your head, it might suggest not getting too ?ahead? of yourself in a situation or that you are having bumps in your understanding of the world. This portion seems to go back on how you want to escape the stresses of real life, but with more qualities. I think Armin might be referring to a need to be curious and venture out and also being concerned about the safety of friends. You consider hiding your injury and you go through a tunnel, opening yourself to new possibilities and freedom.
Then you walk alone and an old woman tells you to stop hanging out with the Attack on Titan characters. You seem to be going at a steady progress towards your goals, but the old woman, the symbol for wisdom and guidance, stops you in your tracks. Perhaps this wisdom of not hanging out, which is representative of a winding down or relaxation, suggests that you might have relaxed too much and should be careful to not get too lazy. However, this wisdom might be making you anxious since forgetting represents an overwhelming amount of stress and feeling the need to tend to everyone?s need. Forgetting something can also be your subconscious telling you that you actually forgot an appointment or date. You thought you were with a frog this whole time, which represents potential for change or the unexpected. Since it can be related to the frog prince, it can also represent transformation, renewal, or rebirth. I kind of go more for the change and unexpected since not being able to find Armin suggests losing those qualities that were associated with the character or feeling lonely and seeking companionship. In the end, you saw a clown which represents, along with the children, your childish side. Think back to whether this clown was happy or sad as the clown reflects your own feelings. What the clown does represents your uninhibited nature. Since the clown plays with the children, then it represents catering to the child within. If you happen to have a fear of clowns, then the clown could represent someone you think means you harm or someone who is pretending. The children also represent longing for the past and retreating back to a childlike state. You need to spend some time off to cater to your inner child. There were two children, which I think in this case would represent what your soul wants or either double weakness or double strength, depending on how you take childlike qualities to mean. This last part seems to be a call on how you are progressing in your goals. There seems to be a conflict on how much you can relax and how childish you are allowed to be. The wise woman says to be careful on becoming lazy, yet you feel a lot of pressure and stress. This might have ended up with either losing those good qualities or being lonely. There seems to be more lean towards catering to the child within, which can either be a double weakness or double strength.
In summary, this dream seems to be calling to how you are spending your time, whether it be on being more relaxed, opening yourself up to more opportunities, or being conflicted with your stress versus catering to your inner child. There are a lot of qualities being suggested to you, but the stress and conflict in advice is making progress to achieving these qualities difficult. Perhaps see whether you need to relax more or are relaxing too much.
I hope that this helps!
I'm glad that these dream interpretations are helping others out. 
I think you're right...I've been so indecisive and anxious lately, and so much more. The accuracy of your interpretation scared me XD.
