i know this is going to sound dumb, but i've thought of an explanation for dreams and why we have them. crapping starts.... get ready.

the mind has the ability to store data, memory, mostly in photographic forms. well, when i say a dog for example, you might picture a specific species instead of seeing the word dog in your head. you construct your imagination using previous memory of a dog and how it may look like. when you imagine something, you are predicting with the help of your memory as the basis. predictions done during consciousness is fairly simple and logical.

for instance, when i say im throwing a pie at a clown's face, you can already imagine the pie being splattered on his face. thats prediction blended with imagination. of course, it's kinda logical because thats how we are trained to think. you wont think that the pie will turn into a nuclear missile and explode at his face. that's just too random......i said random because its improbable, not impossible.

dreams turn the logic switch off. so your prediction is running loose. and lunacy and chaos is added to it. so your dreams are basically exagerrated versions of simple predictions. so it's not impossible to happen, it's just unlikely......to certain degrees.

which means it is also unlikely for me to be trapped in a room, helplessly waiting to be murdered by a complete stranger by means im not too fond of recalling.
