What is your favorite unexplained mystery and/or craziest unexplained (perhaps supernatural) event that has happened to you?

Unexplained (at least to public) Mystery: UBV-76 Russian Radio Station. It is a Russian Number Station which broadcasts a single buzzing, monotonous, note 25 times a minute every hour. One minute before the hour the tones changes. It's been broadcasting since about 1987 and has only been interrupted on a couple of occasions when it aired garbled, distorted, coded messages and then resumed broadcasting the buzz.

Happened to me:

It's just any normal night, and I hit the hay and go to sleep. While I'm sleeping I start having some intense dreams. All of which revolve around death. They include me getting shot, stabbed, whatever. I have came close to dying before from extreme dehydration, so it feels eerily similar to my real life experience. Not that weird to begin with. Well during the last part of my dream(s), I'm being robbed or chased by a group of people and it goes out into the middle of the street. We've been exchanging fire but they get the better of me and I'm dying in the street. They flee and an ambulance comes, medics start helping me, and I feel like I will be okay. However, I have a strong urge that someone else needs help. I'm not really sure who, but someone needs it more than I do, so I'm trying to tell the paramedics to stop and help them. I start pointing out the back of the window saying they are that way. Unfortunately, they tell me it's too late, and I know they're right. When I look out the window I see who I've been trying to get help for. It's a family friend of my buddy, well call him Mike. He looks at me and then enters a garden with pillars. I assume he's dead and going to a better place. Alright, I'm not so religious at all, but it's what happened in the dream. I wake up in cold sweats, out of breath, the whole nine yards. Later, in the day I go to said buddy's house. I'm about to tell him about my crazy dream, but before I can say anything he says "Yo, Mike's dead." In a really grim manner. Immediately I just become overwhelmed with chills throughout my whole body, and I knew he would not believe me and my dream.
