Unconscious 
To dream that you are coming face-to-face with your unconscious is a very good sign that you are on the right track in your waking life. Things that may have been eluding you are coming to the surface and much work will get done now.
Blackout
Experiencing a blackout in a dream suggests that you're being cut off from something which could be anything from civilization to a specific person or resource. Whatever the case, you feel that you need this contact or resource in order to be successful and you feel 'in the dark' without it/them.
Anesthesia
To use anesthesia in your dream represents your refusal to deal with certain feelings; instead, you choose to ignore them completely. Some matter or aspect in your life is too painful or disturbing to face. You are declining to accept accountability for something you have said or done.
