Dying Upon Respawn From A Save

I hope this reaches someone. In my game there already have been multiple instances where I would Respawn in my world and then find myself dead even though I was no where dead before my save.

First time I was near a zombie villager. Saved the game quickly thinking I could come back. When I came back the zombie had killed me apparently even though I saved when it was good and far away.

Last time, I was on a platform above water, safe. I come back and I have drowned somehow and lost all my inventory. 

It is just ruining my experience. Ugh, I sound like someone complaining to customer service. I hate it. It's just, this game is my outlet. The game I go to when I am upset or need some space from the world. I made my own little story within it and it just sucks when I keep losing all my gear that is difficult to obtain. Hope you can fix this and I hope this reaches you somehow.
