Have you ever had a dream that was so deep, so strange, or so complex, it was really hard to explain? Maybe you saw a big jumble of colors that had a kind of shape or movement to them. Or maybe you were in a place that felt really familiar, but there were so many things around you it would just take forever to describe them all. Or maybe something "worked" in the dream that when you try to replay it in real life, it makes no sense.
Dreams are our mind's interface with what is going on with us at the energy level, so it's no surprise that they sometimes go beyond our rational mind's ability to make sense of them. We feel dreams, sometimes, more than watch them.
