Is this also normal?/genq

I keep seeing black/brown shapes that look like bugs around my room and when I look back they are gone, this also happens with faces and shadows as well. Also, three times now I have heard this ringing/beeping sound on my bed and I know it isn’t the normal type of one where you know it’s just from your ears but it sounds real and out of my control yet whenever I put my ear up to the wall or floor or bed or anywhere it dosent sound like it comes closer or farther away, it just sounds the same. I keep getting the feeling of something like a spider crawling on my skin yet whenever I check there there’s nothing there yet the feeling keeps persisting. I’ve also for the longest time had horrible paranoia, not only with just online stuff as I already told some of you but lots of times when I’m in my room at night I suddenly have the need to close all my curtains to where I can’t even see outside in any of the crevices at all or I won’t feel safe. This also happens but I feel the need to get under blankets cause I keep getting visions of horrible people running into my room and doing things to me. Another thing that happens is I’ll be doing something and then suddenly I feel the need to look behind me and if I don’t for the rest of the night I feel unsafe and if I do look behind me I keep checking there to the point where I feel unsafe and try to go to sleep. Also, with the window and curtain thing: whenever I look outside even when I don’t have that paranoia atm I keep seeing these faces staring back at me and they look so real and they won’t disappear. Also, lots of times I will taste/smell certain things that arent there either but Idc about them as much as the other stuff happening. I keep wondering if this is just that normal thing people say thats like ‘your mind is playing tricks on you’ but I feel like it’s something else.
