Entering OBE or LD

So i am wondering, how do u go from a SP into a OBE or a LD? i heard u have to pull ur self up a rope ur try to float away from your body (OBE) and in a LD u will just see some imagination dream while concious and then go into REM and there on…
but when entering it, do u feel like floating into it? or how do u do that exackly?
-Thanks :smile:
