Robocop - Just finished reading this book -absolutely fascinating!! -there is a lot of quite technical information on there to do with the pineal gland and melatonin etc that I did found a bit of a struggle to get through but it was well worth it for the trip reports!

. .what makes this book so good is the objectional way that its written, im not into reading a 'pro-hippy' 'one-sided' story of psychedelic adventures, I prefer a more feet-on-the-ground approach so you can make your own mind up. this book has also given me inspiration to read further into other 'near death experiences and 'encounters'
btw - If you liked the Alex gray artwork on the front cover, his website hasloads more inspirational artwork on there:
