strange paranormal event, any ideas?

This memory of an unexplained event keeps resurfacing in my mind lately. About 7 years ago my brother(13 then) and I (17 at the time) had snuck out of bed to play some video games; we were completely sober with no prior use of hallucinogenics.

while he was in the living room playing the game I was in the kitchen making a sandwich when the curtains began to move inside the home. Next we heard creaking almost like the foundation of the house was shifting. At this point my brother are standing side by side in the living room when all of existence seemed to collapse moving towards us from all directions. I remember it being like something out of the matrix, completely unreal... yet in a what seemed like less than a second the room had returned to normal aside from the fact that my brother and I were face down on the ground our legs just gave out in that brief moment of confusion and in a panic we just hit the ground. We both to this day remember what we experienced and just typing this out gives me the chills...

I've always supressed this memory I guess as it doesn't comply with our normal experience of the universe, but can't shake the feeling that it was an important event, and that it has some kind of meaning.

Anyone have any thoughts on this?
