Why am I weird???

Bro I was talking to my abnormal psych teacher and he is worried abt me lol. I was like “what’s the normal amount of hallucinations?” And he was like “uhhh zero?” Like wdym?? He suggested a therapist lmao. But yea. I occasionally get hallucinations, delusions, and intrusive thoughts. Like once I fully convinced myself that the apocalypse was going to happen in a week and I started preparing for it. I made an absurd amount of fire starters that night. I also made a first aid kit that I still use. I used to also convince myself that there was someone in my house and I would literally tear up the whole house holding a knife looking for an intruder. And that’s just the delusions. I hallucinate way more often. I see people walking around my house all of the time and one time I heard my friend talking to me while I was tryin to sleep. Not like “ohh I heard my name but idk..” no. I was having a real conversation with someone who wasn’t there. I also sometimes hear faint screaming? Idk if that’s real or not bc I don’t really live in a bad neighborhood. Honestly… I should get therapy lol.
