I have minor hallucinations from time to time where I feel like I see someone in the corner of my eye. It's like a little black spot. I don't know if it's really considered a hallucination because when it happens to me it's more objects or shapes that I misinterpret. For example, I will see a cabinet in the corner of my eye and I will look to see if it is someone staring at me.

Is this psychosis?
