Not the strangest I had, but my dream last night was about vampire-zombies.
A large group, including me, were chased by zombie-vampire, then a zombie bit me, I turned into a zombie-vampire, bit people who also turned into this. Then we were chasing the group in a cliff, but they were cowboys with silver cross-bows who shot at us gigantic arrows (almost the size of a halleberd), then I died, but a voodoo ritual was performing and released the god who will stop this isanity.
I woke up as the god, remove the arrow, got a staff-crossbow-katana, then I flew all over the battlefield to meet the cowboy and the voodoo and we won the war after the final fight in a big tower. Oh yeah and I died at the end because the god's soul left my body.
And it's not even the craziest, I was so much weirder dreams. Most of them look like blockbusters movies.
