What the pineapple am I?

I've had thought of origin of big bang and whatever created that and etc... in high school too. I've made up many theories to the origin of universe. The one I believe now is that nothing exist in this world, we're in a dream world, dream is created by thoughts it is possibly that everything that exists in this world is created by your subconcious mind. If everyone believes in a certain god, then that god would show himself. The earth was flat a long time ago, because everyone believed it is so. The earth is round now because everyone believes it is round.

Some stupid prove of my theory: natural disasters have happened more often in recent years because of creation of disaster movies and more people believes that disaster would happen.
More report of alien/paranormal activities because of alien/ghost movies.

Yea I know my theory is stupid, but it made more sense to me, than god exists.
