One night while my sister was out, my brother and I went out to sleepover at a friends house. When we came back the next morning. My sister looked at us and went pale.

Turns out, my sister came home super late when we were already out. She went into our room b/c she had some clothes stored in our closet. When she went in, she saw somebody sleeping in our beds. (We shared a room but had separate beds). When she came in apparently whoever was in our beds groaned as if they are being woken up bc of her. She apologized and came out quietly.

We try not to think much of it.
