i came to a clearing by the forest and there was a windego - shasqwatch staniding behind the trees - this shasqwatch was 50 feet tall and was clearly seen by myself and my (medicine women) grandmother came forward to let me know that this shasqwatch will let me see him latewr - please intrepret - thanks

Norma to me I would imagine the sasqwatch is symbolic here and means that before long you will be shown a new level and inner secrets will be explained to you. The medicine woman will be helping guide you, to show you the way through the trees to a clearing where you will grow and find your new knowledge. Perhaps you will revisit them soon in another dream or in a meditation.

If I my have a try to interpret your dream little by little:=

A forest here means s lot of trees and foliage= ie: troubles.
Clearing in the forest would mean= some respite.
So through troubles we see a hope.
We then find a tall shasqwatch staniding behind the trees= Something to remind us like tall ruler/ teacher with time ticking.( supported by grandmother= showing re iteration that it is important).
Probably it is your mind reminding you about not taking the easy way about something to be carried out without loss of time.
Probably thinking about some worry carried over the previous day could help you to find your answer better
