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 )

Since the photon doesn't start acting like a wave again after you observe it...

When you observe a photon it is destroyed. And why should the emitter have anything to do with it?

Maybe there is a way to observe the emitting electron that will have an effect on the photon after it has been emitted.

That would give us information transfer faster than light, violating causality and giving rise to numerous problems. And how does this explain wave-like behavior?
