There is a technique that phasers sometimes use to avoid passing out while in the hypnagogic state, that I find helpful- it seems that the feeling of loss of control when going into this state is the feeling of being sucked in or involved with the scene unfolding in front of you. You appear to be having trouble staying there without getting 'sucked in' and lost in the action, starting a 'real unconscious dream'. What I have found helpful (and I realize it's not easy) is, instead of reacting and withdrawing (which snaps you out of it) is to then change focus to the whole scene without paying attention to what's actually happening in it. This is the difference from 'being swept away' at it's own speed (which is how I understand it) to slowly synchronizing with it and maintaining control, which is generally what you want.
