Things afoot?

So, I was going to sleep last night, and around 11:47, I was attempting some grounded meditation. As I lie there, I feel something fall, hear it hit my pillow behind me, feel it brush against my hair as it fell.  I could even swear I felt the pillow shift from where it landed.

I got up, and turned on my light.  My pillow looked normal, nothing on it, picked it up, checked behind it, checked underneath it.  Nothing.  The closest thing I can imagine that it was similar to, was an arm, falling from above, brushing against my hair, and hitting my pillow.

Shortly after, I attempted more meditation, and had my left hand move oddly and poked myself...

Just an odd night I guess...

I think I figured out what happened last night.  I have something that I hang from my window.

One of those things.

Anyways, it fell, landed like so behind my bed

The odd thing is, there is only this much space between my mattress, and headboard.

And, this is where the item is hung.

Also, this is how high my headboard is.

The window was open when it fell though, so I have to take that into account.

There is also this much space between my window, and the headboard.

The thing is it is large enough that when it falls it can land across my headboard, and my windowsill. So I have to take that into account, and the fact it is a rigid piece of metal, so it could have bounced hit my pillow, and fell between my mattress and the headboard and landed on the floor...
