Strange Noises

We moved to a new house in July. It's amazing how many new noises you hear when things change. The most annoying to me is a banging noise coming from the vents. I only notice it when I am in bed. It happens every five seconds or so. I've pulled up the vent covers, vacuumed everywhere I can reach, etc. but still the banging continues. If you have any ideas, let me know.

The lastest though is a sweet noise - a tiny ghost sound coming from the kitchen. I guess Ty didn't get the memo that Halloween is over. :)
