Ignore and go back to your room

After waiting to listen to see where the strange noise came from for a few more seconds, you hear nothing and give up. After downing a soda and a pop tart, you head back to your own room, making sure no one else was up and about.

This caution was due to the fact you had a certain hobby, one your family didn’t know about, and you wanted to make sure it stayed that way. You closed the door to your room, thinking you locked it, you go to get out the tools of your secret hobby.
