Do it everyday when you lie down to sleep. I don't set a timer and usually do it until at least my mind is calm (results in better sleep). I listen to my heartbeat in my veins in my forehead instead of breathe, which sounds harder than it is. Also at the beginning of the session it can be difficult to 'relax', so don't even try just wholly focus on listening to the heartbeat even if you need to tense, scrunch up face etc. Then as you get more into it you will relax naturally and fully. Hard part after that is drifting off into memories, which takes experience to lessen that. Effectively you get better at observation, which leaves the unconscious free to do as it likes and it can get up to all kinds of weird stuff. I've observed it playing a racing game and controlling the car and overtaking other cars. Or sometimes it'll jump me into a lucid dream state, (where you know you are dreaming). You are never quite sure what it'll do.
