Some explanation first: this dream's other main character was my old biology teacher from high school, whom I like very much. She's a sweet, slender woman in her 50s or 60s, with short, black hair. Also, a backstory for the world itself: giants live in the mountains. They are creatures whom are usually not hostile, unless provoked. They can live very long and a lot of individuals still living today have witnessed the evolution of humans from the beginning first-hand.
I was late with a school project and she agreed to help the next day, when the class would go on a trip. She gave me two, spyglass-like cameras, which I put together to be able to make 3D footage. We departed on the trip together. She took me to the meeting point by car, which was at the side of a road, in a forest, in a valley between two mountain ranges. The other kids and one other teacher (a male who had a Thanos-like head) were already there. Just before arriving, we saw some giants from the car and drove very slowly in order not to provoke them. However, they still became somehow agitated and followed us to the meeting point, where they took the male teacher, stabbed through his mouth with a stake, then took his head off and pinned it to a tree. They then started murdering some of the other students, while loudly reminiscing about how much more fun it was interacting with humans millions of years ago, when they were still made of stone. My teacher had vanished somewhere, so I started running along the road. The giants turned into huge rock formations after a while, lining the neighbouring mountain. I think they died, somehow, but they looked very intimidating still, the formations resembling huge, roaring heads. One of the formations further along looked like it was laughing.
I continued along and seemed to have stumbled upon some of the surviving students, who proceeded to continue the trip, regardless of what had just happened. We were taken along an obstacle course, consisting of climbing along platforms and inside of narrow and rectangular clear pipes. Still worried about where my teacher had went, I outran the others and found a door, which, as it turned out, led to her flat. There she was, but she had hanged herself. I ran outside, but then turned back and found a suicide note which read ‘Thank you for attempting to save me, even though I was already dead.’ Confused about the note, I took her body down and laid it on a bed.
…She woke up and revealed that she was only hanging on a trick rope, and that she is actually a secret agent working for ORFK and that she was well-equipped to deal with giants. She then got up, we got in her car, and drove off into the sunset.
