So it has been the past few years I have been experiencing this. There is no pattern to it. It has happened a few nights in a row and then most of the times there can be days to a few weeks between these occurrences.

I would be almost asleep in bed, kind of in the in between state where I'm relaxing my mind, I'm breathing slower, just your basic process of trying to fall asleep, and then I would feel the bed shake. Like someone is standing at the foot of the bed consistently nudging it with their knee. Usually it lasts for about 1-3 minutes. I thought maybe it was me moving, so I tried a few things like paying so much attention to my body laying completely still, to holding my knees up to my chest, to sitting up in bed. And still the bed keeps shaking. I just can't figure out what this could be. I'm never woken up by it, it always happens when I'm just relaxed and sometimes my eyes are even open when it happens.

It's not a nice thing to experience. I don't like this feeling, most of the times I just close my eyes and just cuddle up next to my husband and it eventually goes away. It's not a jolting feeling, I live in Alberta and we don't have earthquakes.

I have experienced sleep paralysis once, about 6+ months ago, where I was lying in bed and all of sudden my arms got really tingly and heavy, and so I just continued to move them and shake them, and then my legs got that feeling too. It was like my body was falling asleep before my mind was. So after awhile of moving my arms and legs around (luckily I didn't wake up my husband!) eventually it passed. This has been my one and only time experiencing that. But this didn't even happen when I had the bed shaking experience.

Is there any explanations for this...I'm healthy, 5'6 125lb. I have no major health concerns in my family history.
