I have a high level of anxiety when it comes to having these types of experiences. I've always felt like, if my mind was opened up to visions of the world events, I'd be held to a higher level of accountability and I would just want to bury my head in the sand. Just like if I had spider sense, I'd get sick of it going off all the time, and probably move somewhere quite, like moon. I feel like the point of astral projection is to expand your consciousness by having first hand out of body experiences. I guess that wouldn't be first hand. I like the idea of flying around and observing things like on a magic carpet or something. I never had much exposure to the idea of astral projection growing up. I blame my early misunderstandings of astral projection on this scene from Ace Ventura 2.
The concept of a spiritual realm has evolved throughout the centuries. One interesting thing I read, on the Astral Plane page of Wikipedia, is that the concept of heaven evolved once telescopes revealed no visible spirit realm in space. "Throughout the Renaissance, philosophers, Paracelsians, Rosicrucians and alchemists continued to discuss the nature of the astral world intermediate between earth and the divine. Once the telescope established that no religious heaven was visible around the solar system, the idea was superseded in mainstream science." I always assumed heaven was thought to exist in a separate realm. It would be funny/scary as heaven if you could just look up at the sky through a telescope and see God staring back at you, waving his finger saying, your cheating!
