I have just found out something about dreams. Let me first try to recall my dream first.
I was chasing a larger-than-life candlestick around some large cavern. That candlestick was taunting me and forcing me to do something that I just don’t want to do. Throughout this mindless, aimless conflict, the candlestick said repeatedly, like 4 times, “Hello, friend.”
And then I woke up to sms-es sent my by mum who just happened to wake up real early and started web-smsing me. And my freaky sms tone currently is “Hello, friend.”
How interesting. Sounds that my ears heard were ‘converted’ into sounds that played back in my dream scene. Maybe that’s why people can sleep through noise – your brain converts noise from the surroundings and plays it back in your dream.
