Has any one else ever done something like this?

So, I have this little bookshelf that's like 6 inches taller than my bed which is at the end of said bed. I wake up at like 3am to hear a huge crash, and I of course panic and look around my room to see the book shelf crashed into my desk. I had kicked it over while I was sleeping, and it's pretty hard to kick that thing down! There's actually two dents from my feet now, which is odd. Has anyone else had an experience like this? Is it something to be worried about (I worry about everything haha)? Thanks!
