You have some very interesting dreams Alisa. yes

Leprechaun is the name given to the little gnome like person which is found in Ireland, and appears to be attached and works with 'earth' tasks.
Every country has it's own name for them.

Similar types can be found all over Europe and USA and Australia(ongoing research).

Personally, I do not think the Leprechaun is of the 'Green Man'
status. I would attribute the 'Green Man', more to wood and forest spirits.

In my mind, more likely to be tree orientated.

My twocents on this topic.
