I have this multiple times a day, I always see something walking past me in my peripheral vision.

I, too, see a lot of things that really aren’t there and end up scaring myself half to death. I also have been experiencing an increase in auditory hallucinations and those are also a lot of fun 🙄

This was one of the many reasons I was diagnosed with schitzo-effective disorder

Yes, I would often see a blond man in a bright pink shirt. I tried to talk to him several times because I thought he was real, then he would disappear right in front of me. One day, I saw him lodged in a tree, as if he had teleported into the trunk of the tree accidentally, and that was the only time he wasn’t smiling. I didn’t help him because I recognized him from before, and therefore knew he wasn’t real.

I have a bunch and they are always different. I only had one that would show up repeatedly and it was a young woman or maybe a teenager dress in white with black hair. She was always screaming, crying, or just sad. I've chased after a few thinking they were real or out of confusion. My mom came to check on me once while I was sick. She pushed the door open slowly, peeked in, then walked out and into her room and turned the light on. When I walked in after her she was gone. I walked in after her because something felt off and she didn't answer me. I saw her hands wrap around the door instead of the handle. Her hands were dark, long, and looked sharp, but I ignored that thinking it was maybe the shadow of them or because of the dim lighting. Also, her eyes were lower as if she was shorter and they had a faint gold glow, which isn't actually abnormal for her, but more convincing that it was my mom. And when I went to her room, there was no light on. I checked the house after and no one else was there. Just me.

Every day, especially the darker it is for me the worse mine gets. Or when I’m alone and see or hear something close to me.
