actually in one of my theories i believe the human consciousness may be able to perceive more than our physical 4 dimensions. One brilliant mind came to a theorized conclusion that certain things such as gravity or dark matter is multidimensional. They are not bound by staying in only 4 dimensions as we are not bound by staying in one physical dimension. But our brain and consciousness is a complex tool that could very well work the same way. what if our mind can exist and does exist in every dimension? or at least more of them. what if our dreams are another reality. what if our thoughts and feelings come from other dimensions?
i believe 5 or 6th dimensions define choice. a timeline pathway that we take. for every decision we make or have branches off into infinite parallel universe. but i believe you are only you. your consciousness can only exists in one place. if you could copy your brain into another person, you could NOT be both. you have one "SOUL". so are there other me's? well eventually i broke past this stage of thinking. what if we exist as ourself in every universe or dimension at the same time, and we collect and switch through them, or at least have the power to? you would have done everything and been everywhere, thus making us almost godlike, holding Akashic records in our own selfs.
either way if our mind is a gateway, can certain drugs help us use it?
reality isn't as easy to perceive as you think. the world is not as solid and concrete as you think it is. think about how paradoxical human personality can be. everyone is equal, i dont believe in hypocrites, why is someone bound to be one thing and not another. their not. everything has a balance, and if this is true, for everything that is, is also isnt at the same time. further following this. we just think a certain way because its all we've been taught or raised to believe.
