There is a kind of dream that I am finding it hard to understand. You dream of a scenario and then you find that that scenario is farmiliar. When you get up, you neither remember the scenario nor understand why the scenario was farmiliar.
There is also another one I may recall the scenario but I don't understand why I tended to recall something while dreaming. I might dream say visiting someone and within the dream, it is quite farmiliar that the person had invited me. When you wake up, I don't remember the dream wherein I was invited by the person. I only remember the dream of visiting the person and that during the dream, I was farmiliar with an earlier invitation.
