This question assumes that you will be ‘put you into some deep, deep sleep’ to access your unconcious mind in an effort to reprogramme it.
This is not what I do.
I work with natural trance states, like when you are on ‘auto-pilot’. As my client, you are just having a conversation with me, whilst sometimes having your eyes closed. This is just using your own natural ability to use everyday trance, which makes your unconcious more accessable. You might, however, end up feeling a little more relaxed as part of this process.
