Exactly. I don't expect the chain to keep someone out. I expect it to wake me up if I'm asleep.
Three easy rules have kept me safe:
1) be aware of your surroundings when entering your room.
2) chain the door
3) take valuables with you or put in safe, but know they are only marginally safe
I'd also add to know where the emergency exits are.
