As you will all notice most precognitive dreaming claims are about something that happened "a long time ago" and are usually not "realized" until later on that it was a future predicting dream...

I think it has to do with how we associate time. To be frank there is just NO way that you can accurately date when you had whatever dream you had. Unless you write this down in a journal or have it connected to something that happened the day you woke up...there really is no way.

Based on this information I propose that so called precognitive dreams are the product of dreams involving events that actually already happened and it is just your inability to connect it to a real time line that distorts your perception of the fact that it is actually a post-cognitive dream.

I have not proof read what I just wrote and I don't intend on making it make any more sense .
