the only thing I could think of was like them being afraid of your “soul” becuase lucid dreaming might not be a “whoelsome” or “Christianly” activity, meaning, occult, evil, witchcraft, magick, etc…
I can’t say I’ve met Christians like that (aside from on Harmony Central forums, but the topic was astral projection and how many of them have heard of or “knew” people who were possessed by Satan because of it) though… but I’m sure they exist.
They are probably superstiious folk that think you can get trapped in a dream, or trapped out of body, or killed in a dream and die in real life… I suppose… lots of people do believe those things, or at least, worry about them a bit.
Actually I talked on another forum to a guy who was scared to lucid dream because he was lucid in a boat once and couldn’t wake himself up, and then things got progressively scarier as he panicked and he fell off a water fall, waking himself up…
So… yeah, those people exist, it baffles me that they would have this ability to go back and FIX THESE IRRATIONAL FEARS and that they would run from it though, I mean, yes, it can be terrifying sometimes to explore the unknown like that, but just doing so shows you that there is a flip side to the negative and that with a few more tries you can completely erradicate all these fears and you know, learn so much about yourself.
and with that damn upcoming Drew Barrymore movie about a guy getting stuck in a lucid dream forever… well, these things will just get wrose, as the kind of dream phobic people tend to be susceptible to all sorts of unproven third hand wives tale like gossip and conjecture and superstition.
