i am confused, right now.

what is a visual delusion?
or is this another way to say visual hallucination?

i am wondering because ive heard some say that
BUT, ive had things actually in front of me change, like my whole environment or more than half.
i have interacted with it, too, sometimes

is that a visual ______ (whatever) or?

also, i can sense people that i know in real life (in reality), it feels like they are really there when they arent physically with me, so i talk to them. i do not see them but i could swear they are there. i believe they are watching me. i cant see them but they see me.

comparable to if i was locked in a room and there was a camera in the corner. the person, may not be there and may not talk, but i KNOW they see me, I KNOW they are there and watching, listening, observing. you know?

i swear i know they are there, and i cannot do stuff, with them watching. like i know exactly who it is each time they come, because they are real. they are people that i know. i cant do a thing, even say, use the bathroom and they stay there for hours sometimes. its like i can also sense when they leave.

i think they also remember our conversation next time i see actually physically them, and if i dont bring up things i talked about, to them, they try to read my mind to get it out of me
