The only way to know for sure what would happen is to allow yourself to be sucked in. It sounds like it would be an interesting experience, but naturally from the perspective of reading about it afterward I can't know how it actually felt.
The only technique I learned for going out of body from a dream is to dream that you are going back to your body and then do a projection technique to cause separation. It is supposed to be easier than doing it from a waking state. Waking up somewhat if it happens on the initial return to the body will also help with the chances for recall later.
