I lay in bed, reverse blink, get really tired quickly.

Shortly after I start to see random white lights float across, and random sounds (mostly inaudible voices), i feel my breathing get really shallow. Am i going into Sleep paralysis, am i about to enter a dream???

what can i do to stay up at this point??? sometimes i try and visualize (imagining the 5 senses) and outline the dreamworld i want to enter, but it never forms???
