Let me give an example how it is all in your head.
When it first began happening, I realized i could manifest images in my head into the real world. Looking at my car ceiling, I manifested a small flower out of the cloth. I knew it wasnt real, but I could pretend it was real. I took it in my hand. Realizing that these kinds of things were possible, I found that thinking bad things could turn it into a bad trip. I concentrated on my imaginary flower, and turned it evil. I quickly threw it away and promptly forgot about it.
Another example was my friend, Jason. He is the nicest guy I know, but his appearance was scary, especially because he had recently grown a goatee by not shaving that weekend. I grabbed a package of ramen noodles and asked him to hold it in front of his mouth so that he would not appear as frightening.
