Oh, yes! I got over my anxiety overnight by using autosuggestion during a lucid dream! I had struggled with both general anxiety and anxiety attacks for about a year before I did this.
According to plan, I first said out loud in a lucid dream: “I will be happy and anxiety free for a week.” It was amazing, I was anxiety free already in the morning! After a week of being anxiety free, I then said “I will be happy and anxiety free.” This was about a year ago, and I’ve been fine ever since. I am medicated, but my psychiatrist says that it’s actually the placebo effect, because I was on it for over six months without much effect at all.
Also, I master self hypnosis, and I’m probably very open to suggestions, which might be why this was so effective for me.
Please let us know how it works out for you!
