Post apocalyptic movie blender. But why did it have to be zombies?

In last night's episode, it turned out to be a zombie movie.

In the #dream, scene 1 took place at a fenced up immigration queue sort of strategic location. The remaining humans were checking through newcomers for infections, supervised by none other than... Horatio Caine with his trademark hands-on-hip stance. We were attacked by a mob of slow moving zombies and had to retreat.

We pulled back to some sort of a dock. This counted as scene 2 I guess. The city resembles some US metropolitan, partially submerged in water. The water was covered in algae and we were all in watercrafts. A human personnel accidentally fell into the water, and failed to resurface.

It seems nobody expected the person to return as there were creatures in the water. Enter the Hulk. Yes. The Hulk was with us humans. He dived in for an attack, as we all noticed the creature that sealed the fate of our comrade who fell in.

One of us humans noticed we were under attack once again. This time by some wall-climbing creatures that look a bit like the Chitauri (from Avengers). They were jumping on to the sides of the buildings as they gained on us. On the ground were leapers (Diablo 3, Act 1). Once again, we had to flee.

I recall waking up briefly, and returned to continue the scenario.

Oh wow there's actually a scene 3 which I managed to retain. So now I was on a helicopter-type aircraft heading upwards. Turned out I reached a ceiling, concluding that the whole area was under some sort of dome. I climbed into the tight compartment as gravity seemed to not make sense any more. I navigated the confined space of a maze with seemingly no proper sense of gravity, something out of The Labryinth and/or Escher's Relativity.
