I don’t know what phobia(s) I have

Hello, I’m a teen girl who has multiple phobias. I didn’t really notice the first one until two years after the incident that caused it. I won’t say much but let’s just say that I had the window open at night, and I saw a murderer (not in action, just the person). That was when I was 8. I guess at that age you’re just too innocent, and things don’t psychologically affect you until later on. Then at around 11 I realized that I was afraid of deep water, not the ocean in general, or swimming, but just when I couldn’t see the bottom. This one wasn’t that bad, and usually it only takes me a few minutes to get over it. Also at 11 I realized that I was afraid of unknown sounds and when I can’t see into the darkness. This one was the main one. It’s hard to just say, so I’m going to give you an example. Today, shortly before writing this, I was sitting alone in my moms room and the heat turned off. This was fine, but not a minute later, the wall next to me started to vibrate, only the one wall. Like I said, unknown sounds. My brain told me it was just a bit of vibration, my body was telling me to run, and my mind was freaking out. I was getting mixed opinions from myself so I froze. It was a panic attack. I couldn’t move, even though I really wanted to run, but something told me “no, if you run it will get you”. What will get me? I tried to convince myself to just ignore it, or get one of my birds, but I couldn’t move, my heart was beating really fast and I couldn’t talk. This happens to me whenever something similar happens, or when I walk into a room at night and the window is open. Usually I will be frozen for a few minutes, and finally go to close it. I don’t know what to do about this, or even what my phobia is called. I’ve been sitting in the same spot since then, and I’m just going to play a YouTube video to distract me. Usually when this happens it’s when I’m alone at night, and it’s quiet. During the day it almost never happens. Thank you for reading, and if you’re going through a similar phobia, know you’re not alone. Can I get some suggestions? Or ideas on what it might be? Bye!
