The astral plane.
Ok I think i'll talk about my religon for a bit. An important part of Heathenism and Paganism is the astral plane, this can also explain why we believe in the gods.
Reality can be split up into two. We have the earthly plane, which we can consider to be the "real world" and we have the astral plane. When you are dreaming you are in the astral plane.
The astral plane can then be considered to be the place of dreams and of thoughts. Consider this....before you do anything you have to think, thought comes before action even if you are not aware of it. Even when you are wide awake a change in your thoughts can completely change how you percieve reality.
Since our thoughts are what create our reality the astral plane can be considered to be real. In paganism and heathenism (as well as other religons) meditation is an important skill to enable us to try and access the astral plane even when we are awake. Since the astral plane is the place of our thoughts and dreams if we control our dreams and thoughts we control reality
