Hey, SP is not the goal so don't even worry about it... just be ready in case it happens and don't freak out.

About the eyes... just don't worry about them, the less aware and worried you are of your body the better! If you feel like it, try WILD after 4-5 hours of sleep and check if this makes it easier for you

The feeling of entering a dream like this is pretty unique, for me it feels like im sucked by a vaccum cleaner and suddenly appear in a dream... pretty fun stuff
