Sky Cat, in case you feel like reading about your experience from a slightly different angle I recommend:

E. Cardena, S. J. Lynn, S. Krippner, Varieties of anomalous experience, American Psychological Association, 2000.

I recommend Chapter 6, Out of body experiences, but also the chapters close to this chapter. Each of the chapters brings first a description of the experiences with some personal reports, then correlations with personality traits or states, then results from neurophysiology, then more or less all theories (not only the scientific ones) made to explain the experiences, then relationships to other experiences, and finally, the authors' conclusions and open questions.
