Can I believe what I see

Okay people, can I believe my own eyes? I have no idea. I know that I left my body and floated against the ceiling of a bus going from Oxford Road Station to Didsbury. I know that happened, or I believe that happened because I looked down and I saw the top of my own head. Which means either I am going insane, or …………..what? Ideas please people. At the moment I’m starting to believe that I am going mad, or at least cannot trust what my own eyes and ears are telling me.
