I'm been on the receiving end of an attempted home invasion. I shouted at him and prepared to fillet him with a chef's knife if he got through the door. I felt zero nausea before, during or after the incident. The guy had a loaded shotgun in hand. He's either a drama queen or has the nerves of a mouse.
My house has no doorbell but once my wife bought a battery powered one that mounted with adhesive and put it next to the front door. It was a very loud buzzer, not a ringer. One night it rained hard and moisture got into the doorbell. I was awakened from a pleasant dream at around three AM and grabbed a revolver from the nightstand and went straight to the door yelling that I was going to shoot the SOB who was holding my doorbell down in the middle of the night. My wife was yelling at me to stop, she had already figured out that it was moisture in the switch causing the bell to go off. Her yelling woke me up enough to realize I didn’t need to kill anybody. I don’t do very well sometimes when I am awakened from a dream!
Needless to say I got rid of the damned doorbell.
