Tons, of which especially thanatophobia. The thought of not being alive anymore, including not being able to sense anything anymore, makes me paranoid as ever, and whenever people try to discuss death where I am (they all think it's "normal" and "part of one's life"), I try to evade it as much as possible because it just makes me feel so scared, and then I eventually realise too late that I could've just said something in the way of "could you please not talk about that, I'm paranoid of death".
I also have severe lepidopterophobia, which first manifested on a holiday in France in 2008 when a butterfly suddenly entered the holiday home but my caretaker refused to remove it while they knew darn well that I felt very afraid every time I went up and down the stairs, since the butterfly was on the window above the stairs the entire time. This fear became gradually worse when seeing moths near me and such too often for the subsequent years (my very own bedroom became almost entirely infested with moths out of nowhere in 2015, eventually forcing me to sleep in the living room for almost over a month), and even when playing Animal Crossing, I still (try to) play it by day as often as possible in the summer because I even get scared of the moths (especially the oak silk moth) that I see there, despite it only just being a game.
Similarly, I have pretty severe entomophobia (
absolutely not to be confused with emetophobia) for the majority of other existent bugs, of which mainly stick bugs (with which it first manifested when I was nearly 8), cockchafers, silverfish, ladybirds (a petit restaurant where I used to 'work' for about 10 months from August 2016 to June 2017 was majorly infested with those during the winter), caterpillars and other larvae, mantises, crickets... but especially wasps whenever the letter S is included in the name of the month (August and September), because that's where they become extremely aggressive and especially come near you when you have a bucket of candy or chocolate sprinkles on your lunch sandwich!
So yeah, because of those two phobias, I either keep the windows and doors closed at all times, or only open them up whenever there's anything in the way of a net in front of them, to completely repel the bugs.
Furthermore, I have arsonphobia, which I discovered when the recklessness of fire and the loss of belongings in its process were being discussed in science class way too often in my last year of school overall (10th grade), coprophobia (mainly when it involves an animal's 'bodily waste', this most likely manifested when suddenly seeing a very explicit and uncensored (the Nether really doesn't know how to censor visual explicit content...) announcement for some horror show about animal hoarding on TV in the evening, aka the worst time to even promote that when you're aged 12 and about to head to bed), necrophobia (yes, also when it's Yuri's death as seen in DDLC), moderate trypanophobia, acrophobia, aviophobia, trypophobia and claustrophobia, slightly severe haphephobia (which is most likely fairly common when you're autistic like me), an overall phobia of sirens (because of Siren Head, is there even an official name for it?) and lifelong achluo-/nyctophobia. (Trust me, I am still mandatory to sleep with a nightlight because I become very anxious of the unpredictability of the dark.)
...I really am scared of a ton of stuff, huh?
also when i was you ger i was very scared of darkness but i grew out of it
