Okay … SHORT dream this time, since I can barely remember it:

Jameson (and again he was younger than he is now) had a cobra in some sort of holder hanging from the wall. The holder was more like an envelope, actually. The cobra was rather small, although wider than I would think a small one would be. I freaked out, but then I was told — I think by some scientist although this is all very sketchy — “It doesn’t become dangerous until it starts playing the trombone.”

Right.

Later Jameson had a poisonous spider. It, too, wasn’t yet dangerous, although I don’t recall what it’s danger sign was.

Yes. I have strange dreams.
