What is everyone's take?

I'm just curious on everyone's opinion on the functionality of this projection/lucidity/obe, whichever you choose to call it.

I've chosen a select few people to share my stories to, and have had good responses for the most part (they don't think I'm crazy) but my mom does. She just can't see the point, though I know she would feel different if she had any idea what it feels like. I know I blew people off in the past when astral projection and lucid dreaming has come up, but now that I know what it's like, I obviously have no doubt of the realness of the experience.

Part of me views this as just a past time; a fun and interesting game I play by myself, separate from the rest of my life, a way to trick our minds to be more conscious of our dreams.

However, if I'm honest with myself, I can't deny the spirituality I feel each time I do it. When I come to and every inch of my being is vibrating, I feel liberated and happy, knowing its time to go off on some sort of adventure. Or the power I feel when I become lucid in the midst of a dream. We have the whole world at our minds hands, with no consequences for waking life if we should make mistakes.

I know it isn't useless..but what is the purpose?
