It's been a while since I last had a bad dream and the one I had last night was incredibly vivid:
I moved to a new apartment and went to a nearby mall to buy some groceries. The shop I went to was on the top floor so I took the elevator. Did my shopping and went home, but then I remembered I forgot the soap. So I turn around and enter the elevator once more. This time, a construction worker and 2 nuns enter with me as well. We reach the top floor, but when the doors open... it wasn't the mall.
It reminded me of a subway tunnel, but without any tracks. All four of us step out. I was pretty confused so I asked one of the nuns if the shop I'm going to is nearby, to which she giggled ominously and said good luck. Walking a bit further through the tunnel, I saw a corpse on the floor which was pretty shocking. Then a few meters later, another identical corpse... then another. About 6 corpses later I reached a widened area of the tunnel which resembled a decrepit living room with a worn sofa, armchair, tea table and an old TV. I decided to take a seat in the armchair and soon a man resembling the corpses comes in and takes a seat on the sofa. He was also very confused and disturbed by seeing a bunch of his corpse. A woman then cam as well and told him he wasn't supposed to find out he was a clone. She pulls out a knife but instead of attempting to murder the man, she turns to me and swings.
I grabbed the knife by the blade, cutting myself badly, but somehow managed to tear it out of her hand. Without hesitation, I immediately ran the knife through her throat. The man was terrified and prepared to run away, while I stood in front of her lifeless body, shaking and on the verge of crying about what I just did.
For better or for worse, I woke up afterwards and actually felt the tears about to form in my eyes.
