We have a lizard shaped bell decoration on our front door and it only makes noise if the door opens or closes. Im laying on the couch tryna get sleepy n the fucking thing jingles loudly and im like wtf n look towards the door (with my blind ass eyes cuz no glasses on in the dark) n im like i didn't hear it open n know i locked the door. Took that down for the night. Its been up there for 2 months and never made a sound n its kinda heavy so you gotta bonk it to get a noise that loud. Guess one of my dead loved ones or pets was saying hi. Still spooky tho.
