Neon Eon, If you stare at something, you will see a glowing outline. Called an after image and when it moves, it stays for a little while. Now if you spontaneously see this, then that's something.
As far as higher levels of conciousness... well... good luck with that. I don't mean to be a downer or anything but look at all the people who claim to have "higher levels of conciousness" and.... what has it gotten them? They claim to do stuff and see things, but really if you go to those types of forums you'll see a LOT of people that are just ...nuts.
I honestly believe in Astral Projection, because I've done it. I also believe it's probably a biological function. I think it's tricky as hell to do, but it can be done, it's legitimate, and it's been reproduced in a lab. I also believe in Chakras and stuff, because I have the opinion that if you believe in something like that, it's true. Psychosomatic responses are really amazing, you think you can feel your Solar Plexus, and you do. Or maybe it's totally real, or maybe it's only real to those who believe it is, or maybe it's not real but people think it is. Who knows? Do what makes you happy, I say.
Look into awakening your Kundalini. Fascinating. I REALLY need to get back into the groove and start practicing AP again. It's hard to get into nightly practice since it's such a disproportionately rare event to the amount of time you try. It's also easy to get scared when the vibrations start and you enter a trance, and that makes you breath faster and your heart race and before you know it, you've messed up what you've achieved over the past hour.
ALSO, get a pair of good headphones and try this out. It's the BEST free binaural sound I've come across.
And before some of you guys say I'm crazy, don't judge before you try it out honestly for a few months.
