I firmly believe invega causes dissasociation. Parts of your brain that would normally communicate can't. This caused an inability to draw correctly for me, I was horrified to see that I had forgotten something I spent years learning how to do. (I can draw again now, its's like riding a bike to me, rediscovering a lot of things like my old memorization techniques too) It came from a lack of connection, drawing takes multiple parts of your mind and body working in concert.
So maybe the way it blocked connections left you with this. I'm curious about the details of your experience are. What did this consciousness text you?
I have two friends with DID (formerly multiple personality disorder). One of them makes full switches and the other more often has "co-pilots" than full switches, but it's not the way you describe. If you don't mind disclosing, do you have a history of severe environmental trauma such as being a small child in a war zone, childhood sexual abuse and/or severe neglect? Just to rule out DID.
