I believe I have read something about this. What you may be expirencing is the beginning of entering the trance state. As Robert says, you can feel like you are in a much bigger place, and you will feel as if you are expanding. Not his exact words, but around there anyways. This maybe what you are expirencing. I don't, however, remember him saying it was a scary thing, but like most things, if you don't know what they are it can be very scary.
