You ever seen this picture?
Or this one?
We have a 3rd eye. Not on our exterior, but our interior. It's called the "pineal gland". It's located in the lower part of your brain, in between both of your eyes. (Hence the 1st picture). It's also triggered by light. (Hence the 'enlightened' eye on the back of the dollar bill)..... This gland is active at birth and as time passes and we age, it deteriorates heavily.
There's meditative techniques to help restore it's function, ancient cultures know this, ancient Greeks even called it the "Seat Of The Soul". Ancient schools believe it's the link between our world and the spiritual world. Anyway, you can look online for the various meditation techniques.
The crazy part:
I've been meditating the past 6 days and for the past 5 nights I've had dreams where I can fly. Not only can I fly, I have complete control over my dream. It's called Lucid Dreaming, and I could not do this before 6 days ago.
