Can we use lucid dreaming to delete an unpleasant memories from the past from our brain? Or at least change something in them?
I don’t know about deleting them but maybe if you go through this experience again in LD where you’re going to have full control maybe you will feel better about it… There is nothing to lose if you try…
Well, I’m gonna try…(when I manage to get lucid without waking up 
!
I heard that it can be used to cure diseases. If this works, lucid dreaming sure would be the future of medicine.
