Likutei Sichos Vol 01 pp 85ff Dreams and Golus.

Dreams, confusion of realities. However this also reveals higher source. It doesn’t discredit one’s work though. Page 85-6.

The idea is that in Golus the good is forever and the bad will pass making it unreal even before it’s been eliminated. The lesson: all good is good and don’t let the not so good discourage you. Page 86-7.

The lesson from dreams: Grab and eat; grab and drink in Ruchniyus. The extra light actually helps wake up from the dream. Page 87-8.
