Did you know about lucid dreaming before having the dream? I see how that could be a frightening experience. I believe that misunderstanding this altered state of consciousness has helped build all kinds of mythologies. Alien abductions, demonic posessions, glimpses of the afterlife. Many of these accounts read a lot like a sleep paralysis/ lucid dream scenario. If you were a superstitious person, and had no knowledge of sleep paralysis or lucid dreams, what would you have thought of your experience?

Hopefully you can overcome the frightening feeling of weirdness, and learn to turn your future sleep paralysis and spontaneous lucids into fun adventures.
