When I was 24 years old I had an experience I will never forget. Anyone reading can make of it what he/she will.
I was sitting cross legged against the wall of my bedroom reading the bible. There was nothing extraordinary about the day. As I was reading the bible something thick and heavy came over me and in my sprirt I saw an airplane fall from the sky. It came crashing through my bedroom wall and into me. I was so horrified and confused that I ran into my roommate's bedroom and started raving hysterically and I told her what I had seen. And that I believed that something bad was going to happen. She calmed me down and assured me that calling the airport was the worst thing I could do. I agreed and then just prayed. For the rest of the night I was dumbstruck by what I had "seen".
Well the very next day, about 20 miles north, a small Cessna collided with a commercial airliner and fell into a track of homes, killing several and all aboard the planes.
I have absoolutely no idea why I "saw" this happen but if anyone asks me does God speak to people through dreams, or visions, my answer is obviously Yes.
Thankfully, that was the first, and last, thing I have ever "seen" before it happened.
