I have woken up from sleepwalking cooking eggs....doesn't sound all too crazy, but think about it. I had no awareness as to what I was doing, and I managed to get everything out and start cooking before I woke up. I was glad I woke up to burning eggs instead of burning skin from spilling hot oil all over myself.
I have had some pretty freaky fever hallucinations too, but lets not get into that.
Glad to hear your snake didnt eat a thermometer.
