When I load a save state I spawn in the air and fall to my death.

This is the second time this has happened. I loaded a previous save state to continue building my world and after loading i was far above my original location (which was underground at about 28). I can see that my spawn was not where i originally was and i watched my character fall from the sky and die and lost all I had. My last spawn location was over 4000 blocks away, I did that so i can later connect the area I am building by rail. I don't know if anyone else is having this issue. Also every time i load my save state i can see my save loction int he picture but load back at my bed even though it has saved over my save.
