Very frustrating! I had quite the dream about Bigfoot -- I even had a lucid moment in the dream where I said to myself that I can't wait to blog about this dream -- and of course, cannot now remember anything about the dream. Except that it involved Sasquatch, with a strong emotional component.
I'm fascinated by the fact we can remember that we had a dream, can remember that it was important, or frightening, or had to do with a specific subject, but we can't remember the actual dream itself.
And yet that dream exists somewhere. It happened. It's a memory. It's lodged somewhere, whether that somewhere is in our minds, or on the astral.
