OK most people are familiar with the accidental intoxication of Albert Hoffman and the purposed discovery of LSD. Well I've had something bizzare and similar happen, and am trying to retrace my steps!!! I was outside sweeping the verandah, when I decided to come inside and use the PC. Having come straight in from the bright sunny outdoors I wasn't surprised at the fact I my vision was a bit off, seeing those blue spots when you go from light to dark. Sitting at the PC I had to blink as I could see slight motion out of the corner of my eye, decided it was nothing. Went to write on a piece of paper but had difficulty as I couldn't focus on where the nib of the pen was due to circling kalidoscopic 'broken glass' effects in front of me. At this point mentioned to my wife "something was up" she looked at me with an kind of wtf are you going on about look. Anyway this started to peak at around 10mins where it was very full-on majpr visuals, closed eye ones were bright blue/white with definate sharp edge rotating prisms. This went for another 20moins then slowly dissapeared without any hint of it happening. Now my question is what the hell did I come into contact with?????? All I did was eat lunch and sweep the verandah, maybe got bitten by a strange bug as it was squashed on my shirt (without my knowledge) All I can say was it was extremely strange!
