i possibly wasn't clear in what I said. There are people out there who can project their consciousness whenever they want. Easy to find em on YouTube. When the subject comes up they all say sleep paralysis is the forerunner of the out of body experience -as I know from my own experience. But there could be other causes as well.

Because the person who is experiencing paralysis is in the condition where his consciousness is not linked to his physical body and therefore thinking all is normal he feels he is paralyzed. Scientists because they are interpreters of data will never get past their prejudices on some things. But there has been plenty of research on the out of body state. Many reports through history. Neil DeGrasse Tyson said it well: ALWAYS question authority.
