Yes, I have had these feelings before. And when I was younger (like in elementary school) I would have this image (I was daydreaming) of me riding a bike pass my school and then I fall off the bike onto the ground. And when I fell, I could feel it. It was so weird. I wonder why and how this happens? I haven't had them in a while though. I can only remember me having them when I'm laying down. Thanks for posting this, Suzzie. I thought I was the only one who experienced these feelings. Now I know that I'm not alone.
