Let's take a look at a common definition of the term "quantum entanglement."

Quantum entanglement, also called the quantum non-local connection, is a possible property of a quantum mechanical state of a system of two or more objects in which the quantum states of the constituting objects are linked together so that one object can no longer be adequately described without full mention of its counterpart—even if the individual objects are spatially separated in a spacelike manner. This interconnection leads to non-classical correlations between observable physical properties of remote systems, often referred to as nonlocal correlations.

HEAVY. Thanks Wikipedia, you're the best.

In more understandable terms, we think quantum engtanglement demonstrates the speed of information. Distance, as we understand it, is irrelevant to entangled particles. If you change the spin of the particle nearest you, it's remote, entangled particle also changes spin, instantly. It changes instantly whether it is in the next room, or across the universe, or in another universe, or in another dimension, or in another time period.

Here's more: the speed of light doesn't even come close to the speed of information, because light is a part of our *same old same old* 3D world and therefore it is beholden to d=rt. Quantum particles, on the other hand, come and go from this universe, this dimension, this time, as they please.

The brain is a quantum computer made up of myriad quantum particles. Scads of this myriad (eat your heart out cliff blog!) are entangled.

During the wake (online) periods, a critical mass of the brain's material interacts in a given universe, in a given dimension, and in a given time period. We call this consciousness.

Additionally, this single brain/quantum computer, is online (conscious) simultaneously with a multitude of other brains/quantum computers. And all online brains agree to local laws of physics perceptible by their senses. For instance, "there is a 40ton boulder located at X & Y and we all agree that you can't go through it." This collective, conscious group, constructs the physical world around us at any given instant.

Stay with me.

It's in the sleep periods that things get interesting. During sleep cycles, the brain can leave it's universe/dimension/time for other universes/dimensions/times it is entangled with. Those destinations, as Hugh Everett's "Many Worlds Theory" would have you believe, are all possible realities, including one where your first boss at the insurance company wears a "rat tail" and operates a UHaul rental location in the countryside, and you're renting a UHaul from him instead of working for him and while you're there a fight breaks out amongst his employees in this large field behind the place.

That "UHaul Universe" DOES exist, and is just as real for the individuals in it, as this blog is to the universe you're in right now (although many probably wish they could purge this blog from their universe). In any event, the "UHaul Universe" was an entangled voyage of the brain, a 1st person view through the senses of a conscious being existing there.

Furthermore, we have a name for these entangled voyages of the brain during sleep cycles:

dreams
Finally, certain dreams take place with universe and dimension held constant, but during a time in the future. After the dream, you reach this point in time as an online, conscious being, and you have the feeling, "I've been here before." We call this:
