That would depend entirely on the context of the dream.
If in your dream, you let him boughs your butt it means that you feel attracted to him. If you don't let him than you may have bad instinks for him.
To goose them
You forgot to take the gerbil out of your butt before you went to sleep.
It was probably from a dream you couldn't remember. If you are sure you didn't dream about anything, then sleep-talking is always possible.
The dream is about yourself, and you are the person who feels AS IF there hands have been cut off. This is a metaphor, illustrating your feeling of being made helpless and ineffectual.
to kiss someones butt means to dance
That cannot happen as faeces would act as lubricant
Dude! That's just gross! Why are you curious about that?
