Absolutely, yes - the 'dream' state can entail numerous forms of experience, but some of them are certainly the result of tapping in to the unconscious self. When we deny emotions we force them into unconsciousness where thy stay until we are wise enough to accept them.

Letting go is a tricky process, in that it is also possible to actually deny the feeling parts of the self in the process of letting go and we end up actually letting go of our own essence (by accident). I feel the key is to let go of the light/thoughts/understandings that are unloving, rather than letting go of anything emotional as the emotions are responsive only and so once the source of the problems (thoughts) are cleared, the emotions can then also clear through acceptance/processing without us risking us 'giving them the boot'.. It's a sensitive subject indeed!
