In my experience, things tend to rush you in hyperspace when you focus on them. Hyperspace works in this sort of systematized way for me. Energy (of which entities are composed) moves along my stream of attention. If I'm focusing on a corner of the room, energy tends to flow to that corner. If entities have manifested, appropriately so, attention tends to be pooled on them. If you can find ways to divert your attention from them, you might not get rushed. Using music might help where you can try to really focus on the music, or set it up so the brightest part of your room is not directly in front of you.
