yup, dozens of times. its the remnants of sleep paralysis.

if you lie still and clear your mind it will fully reassert itself, and it possible to WILD (wake initiated lucid dream) from that state once you get the hang of it.

one night last week i woke up from a realistic lucid, felt the 'vibes', entered another lucid, woke up, felt the vibes, and entered another lucid.

check out the WILD tutorial, and you can use those situations to your benefit, and get a lucid out of the deal
