I have an elaborate setup for DEILDs. I have my apple iwatch vibrate for 5 seconds before it automatically stops on its own. It then vibrates each 15 mins. I start it about 4 hours into sleep. If im in deep sleep then it tends not to wake me. If im in rem then it wakes me and i am able to keep still. i then perform 'indirect techniques' until I can seperate out into an 'obe'

'The Phase' is the best book on the planet for DEILDs and combined with an alarm makes it a powerful technique indeed
