You are now in the 2nd one

When we sleep we wake up to another dimension hardly like this one and at that peculiar place we assume we are awake. We remember vague moments of our current actions and call them dreams. When we sleep there we wake up here only remembering the things that are common for both dimensions, but still cannot making sense of them. We assume this one is the real one and other one is dream in each separate plane.

This might look like a wild theory but think about it. Think about what an odd thing sleeping really is. To spend a portion of your day without consciousness or a definite memory. Since we are used to it it feels normal but! ( No need to focus on the little story above, just state your opinions about sleeping )

Pressure

To be honest, I have trouble conceptualizing a wave without something causing it to maintain it's pattern. Light acts like a particle and a wave until you observe it, then it just acts like a particle. the surface of a pond has both the air pressure above it, and the water below it maintaining it's shape. When a ripple passes, it is composed of both water and air.

I get the idea that observing the photon changes it into a particle, but what forces make it act like a wave in the first place?

If you can disrupt it into a particle's behavior half-way from the emitter to the target, then doesn't that mean that it's some relation to it's emitter that'
s causing it to behave like a wave?
