An Underground Temple + Reptilian-Like Creatures + Priestesses / Witches + Dying + Spirit(s) + Being Resurrected + Union + Baby = ?

Last night I remember parts of my last dream which took place somewhere in the day in the wilderness, I think, and I was with a group of people; and the dream seemed a bit like a video game but it looked like real life.

Our mission seemed to be that we were supposed to find an underground temple-like place, and we were supposed to try to enter the temple; but it was guarded and there were traps & motion sensing land mines & alarms.
