When you are in that relaxed state, just before falling asleep, you can ask to talk to someones soul or spirit.
Say everything that is on your mind. Let the words flow, do not worry about how you sound or how they will receive the information. Doing this lets you practice difficult conversations and the other person hears it on a soul level which means they will not be defensive when you have the actual conversation.
This works with anyone whom you have to have a difficult conversation with.
