Apparently I was running some kind of gauntlet/obstacle course ranging from playground-like setups to outright brutal obstacles like in Ninja Warrior, and by the time I reached the end of the course, per-level, there was this eldritch abomination I had to rip to shreds and kill (which, is odd, considering most of them were like some tentacled heart thing with a mean looking eye looking at me with bloodlust in mind). After the hell that was the obstacle course, I had no time to deal with these. So since we had to climb what amounted to a tower, I came up with rather anticlimactic ways to finish them off. Sure you're this heart-shaped demon... thing, and you're the designated enemy; but it doesn't mean I'm willing to fight fairly. So, off the tower you go. They make a satisfying *Splat* noise when they hit the ground that hard. Next challenge, getting down from the towers, that is, until a clear ball bounced my way and suddenly turned into a tunnel (perspective-based activation?) I could walk through back to ground level.
I made it halfway through another course before I decided to wake up. Considering the anatomically-accurate heart-shaped demons, and that today is Valentine's Day, I wonder what that's supposed to represent? Furthermore, I've come to notice this myself, why do I keep fighting these weird-ass things; and for those that can talk, how come I can relate better with them than with other people?
EDIT:
The portal-ball was pretty cool. The lensing effect caused by the clear ball was actually distorted space going inward (along the inside and outside edges of the ball; like how a black hole distorts light). So it always looked like a crystal ball, until decided to walk through it (when it then expands to a size to fit a person), the same lensing was also the inner walls of the tunnel it formed (rather seamless transition from positive-space to negative-space. I think it was a portable 4-dimensional gate made of negative space. Essentially, it literally was a ball of nothing that led somewhere when you enter it. So a portable portal. Funny enough, after walking through, you can carry the portal like a ball again.
I think I was in a live-action classic arcade game made by Taito (brutal levels, and wierd-ass alien monsters all over the place); that's the best way to describe the dream.
