It seems from your description that you have achieved the 'free floating state of mind' Mr. Raduga describes that is necessary for the more difficult Direct Techniques. As he vehemently opposes anyone practicing Direct Techniques until one has mastered Indirect Techniques I would suggest doing what he advises. However, you may not have to start with Indirect Techniques as it seems that you can enter the 'free floating state of mind' easily. If you want my opinion I would say it would be far better to follow his advice and try Indirect Techniques for a while, especially if you haven't had any lucids or full OBE's yet whilst experiencing the phenomena you have described. The reason why you are falling asleep is because you are experiencing this phenomena too passively.

Thanks for the thanks!
