Thanks for the welcome

Lucid Seeker:
1)My dream memory is decent, usually when I have some pretty vivid dreams/nightmares. (there are a couple unforgettable ones that maybe I'll post later). However, I didn't really consider the chance that remembering dreams would have much of an effect of it.
2) As for your #2 suggestion, while I never saw many common things/people/etc ... I often have academic-related dreams, even during vacation! And I don't even realize that it's completely impossible that I would be having a test on New Year's Eve! I'll make sure to tell myself to recognize this sign before I fall asleep.

And hopefully I can practice ... there's so much I could do besides having fun ... stuff that could maybe affect me positively in real life. The only b*tch is waking up, hence disturbing my sleep.

Sandform: I understand what you mean. To be honest, it kind of sounds ridiculous but I'm sure it really isn't.

Zotoaster: It's weird, isn't it? I can have a date where I'm with a female friend when later in the dream, it's not her ... it's a long-distance great friend/ ex-love interest ... and I don't even realize the switch of girls!! On the other hand, I realize I'm dreaming because I realize my class time is different from the one in the dream!
