I havent had much experience with Automatic writing, but I have had one positive experience recently, of all places in the the shower!
I was in the shower, nice relexed daydreaming like I do, and then I felt I wasnt alone. the shower cubicle was all steamed up, but I didnt feel scared.
I just leant back, and felt my hand wanted to gluide upwards, so I went with it, like a involuntary movement. I closed my eyes, not wanting to effect what was happening. My fingers then glided across the glass of the cubicle, i couldnt tell what I was writing, but I went with the flow, I just remember centering alot on my navel as I went in to myself. Then all of a sudden I had a vision of red hair.
I opened my eyes assuming I drew a rune or something nordic as I have been drawing runes recently daily along with my daily tarot, but I saw a abbreviation instead.
L Y M Y
Lymy? what the hell was that I thought. never heard of it before, and I know my internet abbreviations. I figured it was just something incorhenrent. Then I got more and more curious about looking it up.
so once I was dressed, I went and googled it. Then I got a shock.
It stands for Love You Miss You. I grandmother died last year, and she was natural red head!
Thats my only one experience of it though, I have tried again since, but it has been a bit pooish
