The strangest? There are 2 that come to mind.
For the first one, I was on top of some rusted train carts that went across the desert. I was talking to my friends from long-distance as if they were on skype or on the phone with no electronics whatsoever. We found ways to figure out where we were by using handheld lasers and shooting them up to the sky full of stars. Then when I walk down the track of train carts, I couldn't believe my eyes, it was Pinkie Pie. When I got her attention, she looked back with a smile and she was ecstatic to see me. She showed me a spot where we could lay down and look up at the stars. We were looking at the milky way until I finally woke up. This was the dream that felt so extremely positive that I wish I didn't wake up.
For the second one (it felt like I was in the dream for several hours) everyone in my house was missing, and when I go outside my house is floating on a piece of land in the sky. For some reason I decided to jump down, and it felt like a small jump. I landed in the backyard of my old house and find my brother. I ask him what's going on and he said he was looking for our family dog Stanley. We kept jumping over the other neighbors' fences until we find an abandoned mine and find our dog dirted up and ready to die. When I look back my brother tells me that I'm dreaming. I start to debate to myself whether or not I really am, and at that moment I fall to the ground and find myself in (what I thought was) someone else's dream. I "wake up" standing on a building in an oriental-styled city and see 2 people chasing me. We had a chase across the rooftops until I jumped down and hid in the closet of a restaurant and find a gun. I wait until the 2 people come to me and I shot them dead. Then the owner of the restaurant I was in turned out to be my old friend David. He came to me and told me "What are you doing in my dream?" and I replied "what were those people doing trying to kill me?" and he replied back "They were trying to wake you up. You need to wake up so I can take care of business." Then I fell this sensation of falling which woke me up in shock and I said to myself, "What?"
