Respawning in far place after death

I,m using seed 1405023677 to spawn near to a village , after one day of playing . I died near to my house instead of respawning me in my house it respawned in a very far cave surrounded with lava and when i get out of it there was only water and one small island. Notice that i already have a house and i slept in it many times and it was respawning me in it every time.

What i expected : respawn in my last night bed in my house

What happened : respawn in a far island

How to reproduce : i dont know how but it happen sometimes after death

The version is MCPE 0.9.5 ( sorry if i chose the wrong affects versions )

please tell me is it possible to get my progress back and how to avoid that from happening again
