I just thought of this, but it has happened to me several times in my life, and I'm curious as to if this has ever happened to anybody else.
It defies all laws of reality.

Many times when I'm having a dream, something will happen (No really! Stuff happens!)
...something will happen, that coincides with the outside world, and makes a loud noise, however my dream LEADS UP to that moment.

I know that this makes no sence, so I will give an example.
One time I was sleeping on the bottom bunk of a bunk bed. I dreamed that a giant bee was flying around the room. Suddenly, it turned towards me, and flew right at me. Just as the bee hit my face, a pillow fell from the top bunk and landed on my face.

Yes, this could very well be coincidence, but it happens all the time. A lot of times, the event that is happening in my dream is EXACTLY what is happening IRL.

I thought at first, that perhaps I was picking up on some minor sounds that were associated with the events, which fed the events into my dreams, but sometimes I am positive that there are no minor sounds associated with the events, like when I dream that I have called my friend on the phone, and tell him to come over. He says he will be there in two seconds, and a few seconds later, he will walk in and wake me up (I never lock my door).

Does anybody know what I'm talking about?
