I had somehow the same experience in the end of August this year, like yours it resulted through a meditation(Kundalini Yoga) after i watched a very
nice movie Powaqqatsi
, dont know why but it was important for me watching it to achieve this altered
state of consiousness.
I had this state of consiousness for about a week then it slowly went away but I still get those feelings from back then sometimes.
In this state i had no lack of energy, was never tired and if i wanted to sleep it was more like turning off a switch to a dream state.
Also i felt my body like never before, spent many hours in the jumpin arround like a little kid and feeling the oneness of all.
Thanks for sharing your experience, really caught my eye. Hope you can make it back to this state of consiousness. Untill then: Much Love Bro!
