Like a freight train?

Just a general question to the community. Also, this is heavily UPG. When in dream, astral, or OBE, is it common to be hit with a powerful vibration/feeling that stops you in your tracks? I’ve had it occur to me 3 times now, 2 in lucid dream and 1 possible OBE. It is not a painful sensation, in fact 1 of the times it was quite pleasurable, however, it is like being hit all at once and it is almost immobilizing. I can still move and speak with effort, but it takes some will. Is this common when first encountering beings on the upper tier level? Is it something that is related to first opening the senses and your ability to cope increases with more exposure/attempts? Thanks again for all insights :slight_smile:
