dreams

maybe you've heard this experiment before - where someone would write down what they've been dreaming on a daily basis. that'll be interesting to do, wouldn't it? i've tried to do this a couple of times in the past - but i always ended up not remembering what my dream was. i did have the papers and the pen right beside my bed (people say that once you wake up, write down your dreams straightaway before you forget about it) - but not for me. i will remember my dreams after 1 - 3 hours of waking up - that is if i'm lucky. otherwise, i will never remember my dream. this is one thing. the other thing that is interesting is - what makes us to dream? i've been questioning the word 'dream' for quite a long time now - and people has been saying that 'dream is like a thought when you sleep. because while you're sleeping - your brain does all the dirty work - sorting your memories that happened throughout the day into filing cabinets - so then when you wake up, you'll feel refreshed and 'more organised''. if that's true, then everyone should have a dream on every sleep that they had, right? and okay- let's say that i do had a dream, but it's just me who can't remember it - and that brings me to another bigger picture - why can't i remember stuff? how come i forget things more easily than others (which happens to me most of the times during my waking life)? but i guess that statement is not a 100% true. when i do remember something, i do exactly remember what it's like/what processes i should go through (more like a 31% of photographic memory). but when i don't remember something - it'll be just a fog to me. how could this have happened?

so in all - just to make things simple and clear - the things that i might be looking at are...
- what are 'dreams'?
- do we always have dreams during every sleep that we had?
- how come i can't remember my dreams?
- what is 'remember'?
- why do i forget certain things easily, yet in other occasion, i would remember other things very distinctly?
