Bed disappeared - literally

So I was looking for wolves to tame, and so I went and started to explore for taiga biomes. I brought my bed with me so I wouldn't have to deal with mobs at night. After I tamed a couple wolves I set my bed down to sleep in because it was turning dark. I don't exactly remember what happened but I do know that I was standing on top of my bed for one moment, and then all the sudden my player falls down about half a block. I was really confused so I looked down and my bed just disappeared like it never existed before. I tried looking through my inventory and my hotbar but it wasn't there. So I had to deal with mobs the whole night
I couldn't find it in any chests when I returned to my home.

So far this only happened to me once, and I would assume it's an extremely rare bug because I never heard of this happening to anyone else...?

Oh yeah btw in the fields above I listed "iPhone 6" but I was actually playing on the iPhone SE (there was no selective option for it, sadly).
