I understand,But maybe in the next 100 years or so.we could have learned in are brains making us becoming smarter and getting/finding new items such at like plasma.Then maybe we could use a machine to make what we would like to dream,Ex.Like a dream maker.We could imagine what we would like to dream about,use the machine,then go to bed,as for allowing us to go deeper in reserch.I think this has some good things in it.Maybe in the next 500 years ore so we will be so smart we could beable to fhisically make a portal with lots of buttons,leverrs,electricity,and more.I think i got a little out of the whole Mlp portal thing but hey.This might happen,who knows.
