Slow moving HI

This morning I had HI that moved about 1 frame/second, I had just woken up and I didn’t move. I started seeing faces and with every new frame I could see a new face. This slow moving HI happened a second time too, but I can’t remember what I saw that time. This has also happened to me a few times before.

Has anyone else had this, it’s usually very vivid and I’m very close to actually being in a dream. Once I managed to go inside this HI, but it only lasted for 1-2 seconds before I lost it. And I’m totoally aware of what’s happening. I guess that why it’s usually so short, I’m too aware.

Could it be that the brain can’t really keep up, sort of like a slow computer or is it just something that happens to me :confused:
