Your reality is based off of your sense. (sight,touch,taste,hear,smell). And our reality is only based upon what we find off of those senses. If we did not have any of those, then we would be non-existent. But then the quesiton is, how can we trust our senses? We dont know the answer because the info we gather is also from our senses. Humans are natural to have these kinds of questions, because the human ambition is to learn. If it wasnt so, this thread wouldnt be here, and we probably wouldnt have internet. This would also be why scientists are always disprooving themselfs. Well this thread can only go as far as your imagination works, but we dont have a real fact to how this works.
For all we know, we might be little animals, and the entire solar system and everything we know is just an experiment, or a smaller part, of an entire society much larger then we can comprehend.
