Regarding being able to get into a house and not be heard, this is what happened to me.
When I was about 20 I was staying at my parent's house. One night, my parents in their bedroom, I was in mine with door closed. We were all asleep. Cat burglars (LE called them that) came into our home, into my parent's bedroom and proceeded to steal things from the top of the dresser. They removed an entire drawer which contained jewelry and carried it out into an orange grove nearby to sort through it. The chilling thing was that they removed a belt from my mother's shorts which she had left only about 2 or 3 feet from where she slept. This belt was later found discarded with a two by four, which LE said was to use as a weapon, and likely the belt to be used to tie someone up.
Mind you, as a twenty year old, I had tried to sneak into that room while she was asleep and borrow jewelry and that drawer always squeaked and she ALWAYS woke up!
They also took various items from a spare room including a bag that looked like a purse, but only contained a wet bathing suit - I liked that they found a soggy suit when they expected loot.
They made several trips in and out of the house (through the back door they had broken into) even taking an entire case of liquor from the bar.
They did not enter my room, I suppose because the door was closed, it wasn't locked, just closed.
LE told us often these people will wait outside, listening. They know that a certain length of time after retiring, turning lights off, is when people are in their soundest sleep. They listen to people saying goodnight, turning lights off, then wait til the right time.
We had a dog. We did not hear him bark if he did.
It took me 35 years to feel safe in my house again.
I am not at all surprised that all kinds of things can happen in a house and not be detected at the time.
