I had a DILD 2 nights ago, in which I was with a group of dreamers and we were playing some kind of game. It started as survivor, except that it was in a palace in Egypt, we were divided into a bunch of tribes and we competed against each other. We were told it was a shared dream which we couldn't manipulate like other lucid dreams.

It was a long LD, about 3 days long (in dream of course). Suddenly it turns into a massacre. One of the dreamers was an assassin and this DC/dreamer started killing everyone one by one. We had find out who it was in order to wake up, and also (apparently) if we died in the dream we would also die IRL. We were all scared and at the same time obsessed with solving who the assassin was. After 3 days, the dreamers that were still alive, including me, planned a trap and got the assassin, and after this I woke up.

I was confused after I woke up, wondering if it was just a really weird dream which made me believe I couldn't control it, or if it was an actual shared dream. I don't think the part of "you die in the dream, you die in real life" was true, but it definitely kept my adrenaline up during the whole dream.
