Teleportation

Just a thought I’ve been pondering lately; the mind is capable of transporting us to realities that do not “exist” we are capable of dreaming thoughts and people and whole world’s even. So wouldn’t it seem more probable that the answer to time travel/teleportation lies within the mind’s synapses, rather than any external source? The difference between “reality” and a “dream” is merely that “reality” is a shared experience. So wouldn’t teleportation/time travel simply require the ability to “share” these alternate existences?
