I have Lucid Dreams every night. So a few nights ago I took a xanax to help with me sleep. And that night I didnt have any lucid dreams and couldnt remember my dreams like Ive been able to for the past few weeks. They I took another one last night just to see if it prevented me from having any lucid dreams. The same thing happend I didnt have any lucid dreams and couldnt remember my dreams like always have been. Im not doctor or anything like that. I have just a made a small connection. It may be true or not. Im just giving you my prespective.
