Is it normal that i sometimes have flashes of random things at random times?
I will be reading or talking to someone and see a flash of something completely unrelated. It's never an actual thought, it's like someone just put a picture in front of my face and then took it away. I forget most of them, they flash in front of me and I can't remember what they were. The ones I can remember are really random: a person reaching toward me, something big and red (possibly a vehicle), etc. They are unpredictable and have no connection to anything I'm doing. I know I'm not creating them. The last time this happened I was talking and the flash came and I had a "woah" moment because it actually made me dizzy.
(I just had a thought, while typing this that they may be hallucinations caused by some unknown brain damage)
