I feel really tired after a busy night

A friend hasn't responded to a message, sent 3 weeks ago. On
Country File last night there was a film about adders and I muttered at the time "I'll dream tonight". Didin't I! Both triggers.
In the dream: which went on and on and .......... My friend had 3 dogs and a large snake which she wanted put to sleep as she was concerned that it would eat the dogs. This snake was small/huge/large and kept escaping from the pillow case into which she had handed to me to take to the Vet..

. At 1 point I could see its teeth through the cotton material

. Apparently she had owned this boa from a small hatchling and even had it in bed with her

.
This isn't like my friend at all

- dogs, yes. Reptiles, nope. But I was wandering around looking for a Vet Practice with knowledge of snakes; a man let it free 'to run across the grass' well snakes don't run. He then left me to put it back into the pillow case ......... that was a 'no' and I spent ages in the dream trying to find some1 who would hold open the case for me to put this now very large snake back inside.
