It sounds more like some sort of post-dream hypnopompic imagery. Take a look at this (short) wiki article:
Wikipedia on: Hypnogogic and Hypnopompic Imagery.
Basically, "hypnopompic imagery" is hypnogogic imagery experienced when waking up, rather than the usual hypnogogic imagery experienced while falling asleep.. It CAN be accoumpanied by sleep paralysis.
Basically, sleep paralysis is PART of what you experienced, I guess. You also got hypnopompic imagery and sounds. It's a sort of state halfway between asleep and awake. You CAN'T get stuck in this state. It's just a transitional phase.
Hope that helps. :)
