Dream Recollection So Far

So I've started writing down my dreams, the ones that I can remember at least, and it's been really interesting. They say that it's easier to remember your dream if you lay still as soon as you wake up and close your eyes to think about it and record it (found here under Dream recall), however, that isn't the case for me. I wake up having no recollection of any of my dreams and I slowly start to remember them as the day goes on. A lot of the times (from previous experiences, before the WISE project started) I remember the dream in the shower when I'm still half asleep. Other times (probably the other 50%), I generally remember the dream after something reminds me of what happened in the dream. For example, I remembered my dream this morning in the shower, but I ended up forgetting it before I got to write it down. Later today, someone pulled out and old Stats test of mine and I saw it and immediately remembered what my dream was about last night. It's pretty interesting how I can't remember dreams right after I wake up.
