I can usually do it if I lay on my back at night, keep still as if going to sleep, but keeping your mind active. Just try to use your imagination as much as possible, then BOOM. Sometimes right as I got into dream world I get this feeling like I'm getting shot straight into the air and sometimes I get really excited and wake myself up, but I'm getting better at. Its really cool, you just have to have the right mind set and patience.
