Hi, welcome - and well done!
I haven't had the tongue thing, but vivid dreams are very common in early recovery I have read. Alcohol basically makes you pass out into unconsciousness if we drink excessively. Often we don't dream much as drinkers and this actually adds to the mental mess we get ourselves into. When we quit our sleeping patterns can remain disturbed for a while and we tend to sleep much more lightly for at least a few days. With that come a lot of dreaming sometimes. I know that happened to me.
All the best to you again!
