Sometimes when I am in spooky environment (like on a deserted street at midnight with little light), I would have this fear that I would start having hallucinations (like seeing things that don't exist and getting freaked out).
I'd heard that a number of people experience this cognitive delusion and claimed to have seen things like robots with flying heads and that is how they start to believe in supernatural things.
How should I describe the fear I have in those spooky environment?
p.s: I forget to mention I have this increasing anxiety when I am at those spooky environments and so I would always avoid these environments as much as possible (I think this has to do with a part of my childhood..) So I accepted Mohit's answer because agoraphobia describes best how I feel.
At first I wanted to look for the term for the fear of having hallucination but it most likely doesn't exist. (It would still be great if someone finds it and posts it here)
Thank you guys for giving me all the awesome answers!! Greatly appreciate!!!!
