I dreamt that a very large snail was on the floor near my feet. It was without and shell and brightly colored. Jeweled, actually, with large, blue gems. It undulated on the floor and while I didn't feel particularly scared I didn't want any contact with it, either. In my dream it swayed too close to me and I jumped back - - - unfortunately I did, in reality, "jump" back, too . . and fell right off the bed.
What on earth could this dream mean?
