thought related to precognitive dreams
Here is a vague thought about why precognitive dreams are possible.
There are parallel worlds, so to speak, but unlike science fiction ‘timelines’, these are only potentially real. For the most part they’re also not branches off of our history. They’re more like similar histories, what our historical chain of causal events could be if the whole thing were dragged sideways. These potential histories are subconsciously connected to us through our thoughts. When events do occur, the collection of potential histories outlines or constrains what is possible.
