What is so frustrating...when I am very tired and relaxed, and finally do see images instead of just black, I can't help but be a little excited, which makes my brain become more alert, and as a result, the images quickly fade away. But when I somehow manage to NOT get excited, and remain very relaxed, I quickly fall asleep. It's hard for me to stay in the doorway between wake and sleep. Too awake, or too relaxed...the door closes and it's all over.
Thanks for the link...much appreciated.
