This is just a question I ask out of sheer curiosity. I have found that whenever I befriend a denizen (I call my dream figures denizens) I will sometimes see that denizen again in future dreams. Thing is these denizens I befriend have their own personalities and even their own back stories. And they age and mature over the years. I will see these people in my dreams again and again over the course of years and we will always recognize one another. The longest I have known a denizen is twelve years. I have even know some who have started families and I have witnessed their kids grow up along with them. I will also have hostile dream figures who will reoccur and recognize (these are, like, my long term rivals and enemies). It's weird but also kind of cool, it's like they exist within their own little world.

So my question is, has anybody else experienced anything like this? Where they actually make long term friends out of their dream figures or something?
