this is something i did a few years ago when i started with LD.
nevertheless i changed the method after sometime of trying because my mind told me if i wanted to fly i had to go trough the top although SUB seemed a lot easier for me. after a while i forgot it...now it´s here again

your method has another advantage:
thinking of an other world under your bed influences your subconsciousness, so WILDing becomes easier after some time of practise IMO.

thanks for your input...i´m gonna try this (again) in some minutes.
