ohh the amount of theories ive gone through is unbelievable, and these include demons, the slightly less than alive and angels, even the voice of some higher being, such as God, which is extremely add for me as i am an absolute atheist, the only way ive managed to rationalise it, other than thinking it to be mental illness, is to run along the lines that we as humans can never know everything, and our experience of the world is limited to 5 measly senses, perhaps there is more beyond what we can perceive and i am somehow unlucky enough to be more sensitive to these mysteries. however, when it comes down to it, im probably just ******* nuts.
