Dream of snake

Found snakes in a bedroom. At least four snakes, appear to be harmless corn snakes or king snakes. Grabbed two to take outside (one bites me, but not too bad, but I wonder if it was coral snake instead of king), I think it must be a mating thing. Called for my son to come look, but youngest daughter was the only one to come out. I throw the snakes into the yard. They race off in matching movements, racing across yard, but seem bigger now, and suddenly a huge bigger reptile speeds in, chasing the snakes. I think it was a tagu (big lizard but it was longer). It sped toward the house, then seemed to collide with the foundation of the house under the stairs. It bounded out from there, snapped on daughter's leg and tried to drag her away. I jumped on it, pried the jaws open, and freed Samantha. Went to sleep at around 11p, woke from dream apx 12:20-12:25 am.
