This is something I find myself doing quite frequently... I'll confine myself to my closet and plus every crack until there is no light shining through... this aids me to quickly drain my mind of all thoughts. Is there are named used for this sort of meditation?
I'm not aware of any name for it but the technique is timeless. Sensory deprivation helps but it can also give a newbie false positives. The mind, when starved of sensation of any kind, will often manufacture things to keep itself amused. Lights, sounds, etc. Be on your guard there, otherwise enjoy. x
