As long as you were in a comfortable position then it doesn't matter how you lay. I would suggest trying Jeff777's technique first, before trying others. It is one of the most simple and scientific methods out there. If it doesn't work, then I would move on to other techniques. Here is the link: http://www.dreamviews.com/community/...ad.php?t=42271
It sounds like you were in the early stages of the WILD technique, which isn't bad at all for your first time. WILDing takes some practice and patience. Good Luck in your future efforts.
