Just had a shower, I think better in a shower, so let me structure things a bit better:
- The positions of the planes of reality are determined by the amount of psychic power they get from the minds in the lower planes of reality, those versions of reality who get more psychic energy supporting them are in lower planes than those which are less supported, which end up in higher planes. The lowest plane of reality is what we consider the real world, and it is the one with the strongest support of psychic energy.
- Each plane of reality above the lowest one are filled with things that are contradictory to the planes below them. Meaning that the things in any plane of reality cannot exist in any of the planes below itself without producing a contradiction to the dominant reality of the lower one, as determined by the aggregation of psychic power to it's contents (such as making a reality where bigfoot is both real and not real at the same time). Since both cannot exist together on the same plane of reality, the less supported one is shifted up to a higher plane where it could cause no contradictions.
- The minds that exist on any plane of reality can contribute to their own reality and the planes of reality above their own, however, the higher the plane of reality that a mind exists in, the more the psychic power it contributes is reduced by.
- Psychic support that comes from conscious beliefs held in the present is stronger than the other forms of mental activity, but every form of mental activity provides some amount of psychic empowerment to a given potential reality, such as:
- The conscious mental activities that exist besides belief, such as imagination. Imagined possibilities are not thought to be real, but they are still being thought about nonetheless, and so they are still being given psychic energy, even if it's not as much as is given to the possibilities that are being believed in (which means that on some level of reality in this setting, all fictional things, beings, characters, locations, and events are real, and all fictional stories are actually true events).
- The mental activities (like belief and imagination) that exist in the unconscious mind, rather than conscious one, thus from the mentioned categories of mental activity, we have a hierarchy of four kinds of ways minds can give power to the reality of concepts, conscious belief, conscious imagination, unconscious belief, and unconscious imagination (freud and jung would have a field day with those last two examples).
- Mental concepts with a lot of thought or emotion put into them would also be proportionately more powerful than those which have less of an investment put into them, and those which exist in the mind for longer would be getting psychic power for longer than those that were only in the mind for a shorter amount of time, This is why mental concepts that were held for a longer duration of time have more power than those held for a short time, power was given to them over a longer period.
.- Lastly, when mental activity regarding some concept ceases, what happens to the psychic power generated by it towards that concept?
My answer is that the remnants of the psychic energy produced by minds that existed in past versions of the reality on any plane of existence, such as minds that changed themselves (as they tend to do all the time, same brain, different contents), or minds that are no longer active, such as by way of unconsciousness/death, being erased from existence, or being altered by external means in some way (like by the consensus or by mind manipulation) will still exist in the concept they support the existence of, but the concept will lose psychic power over time as it's no longer being contributed to, and will gradually fade away into the higher planes of reality.
You see, if it's actively being contributed to by a mind in the layers below it's own, it's going to be increasing, however slightly, but otherwise it's gradually fading into a higher layer, It's still going to be sustained by the psychic energy that it was given, however, entropy means that this psychic energy diminishes over time, existence needs to be fuelled, and when enough of the fuel is burned up, it gets to be too low to meet the minimum requirements to sustain itself in that layer of reality, it's moved up to the next highest level out, and the process continues.
This is why a god that people worship is stronger than one people don't worship, but still know about, who in turn is stronger than a god recently forgotten about, who in turn is stronger than a god forgotten long ago, and of course, major gods are going to be a lot stronger than the ones who are less popular.
- All of this means the psychic power supporting the contents of the higher worlds can be roughly summed up into four main categories, ordered by the strength of their influence:
1: Supported by the aggregate of the collective conscious beliefs among all minds at their level and below. (concepts that minds consciously think about as being real)
2: Supported by the aggregate of the collective conscious imaginations among all minds at their level and below. (concepts that minds consciously think about as being false)
3: Same as 1, but for the unconscious beliefs of the minds at their level and below.
4: Same as 2, but for the unconscious imaginations of the minds at their level and below.
There could be other differences, including things that would affect the psychic power powering the existence of something, like how many minds support this thing, how recent was their support for this thing, and the nature of the mental activity they used to support the thing.
