Hi Sushupti,
I have done quite an extensive research on the phenomenon of “OBE” (from sleep, WILD and the likes), and on NDE’s. Mixed with my own experiences and that of a few very experienced others, I came to the conclusion (as long as no other “proof” comes to me), that indeed these OBE’s are nothing more or less then a kind of LD (in any case, dream related happenings). If you want to know the details of my ideas in detail, I wrote an article on it which you can get here.
