Doors swinging open is what one expects when one is trying to enter one's apartment.

Again, I disagree. I don't expect the door to just swing open. I expect that I have to turn the deadbolt with a key, and then in a separate operation turn the knob lock with a key, before the door swings open.

While believing you are at your apartment, as you expect to have to turn the key the door swings open, is it possible for multiple thoughts to occur to you? such as:

Geeze! My door is broken!
Geeze! My door has been jimmied! Someone has broken in!
Geeze! Something is wrong and I don't know what it is!

Would you be more inclined to believe your apartment had been broken into if you dealt with things being broken into on a daily or weekly basis?

I think past experience informs subsequent reactions to events.
