Games : I died and spawned in a weird place, i found my way back, but if i die again, will i spawn away from my house again?

Minecraft PE: I died and spawned in a random place. I entered these forums and i used some advice, and i used a compass and found my way back... But what if i die again, will i spawn away from home? Or was that just a glitch? I'm scared of trying to die, bc i don't want to do through that experience again. If i sleep a few more times in my bed, will that help me spawn home once i die? If i hv more beds in my house, and i sleep in everyone of them, does that affect my spawn point? Thx for reading, any advice will help!
