Evocation Experiment, contacting goetic spirits Options

I must say this has been a quite wicked experience. I was thinkin about demons and spirits and came the conclusion as my astral senses arent quite the top notch lol. (IMG:style_emoticons/default/blush2.gif)
I would need to have them contact me while half asleep. A sort of half dream state. So the first time i placed 6 sigils of some demons from the goetia under my head as i went to sleep and said some sort of well homemade unthreathening conjuration.(i choose them specifically for somethings not random) 3 of them answered and well they seriusly can make things clear (IMG:style_emoticons/default/shok.gif) . So last night i placed the whole out printed goetia under my head. Well not the whole just the 72 spirits or how many they were.
Anyways this was the strongest hallucigonen i have ever tried. I think taking acid(lsd) would be less outtripping then what i went trough this night (IMG:style_emoticons/default/insane.gif) .
i am not quite sure i am really out of it yet. Well this wasent really a question but i,ll come to that soon enough.
First this is ment as a warning dont do stupid things just because they sound good in your head and when you do it anyways
dont go over the line and when you also that then say to others not to do it lol. (IMG:style_emoticons/default/diablo.gif)
to the question does anyone have any practical advices on how to improve this technic? (IMG:style_emoticons/default/baby.gif)
i wonder if it could be done a little less outtripping might be a good way for newbies to familiraise them selves whit the demons in question.
i am going to try this whit some necronomicon sigils (seal) (wich is it anyways sigil or seal) as soon i can print them out (damm ink damm goetia being really big)

and would you mind talkin a bit about the experience itself that you had. what made it so intense.?
