Just put some fresh lemon flavoured waffles on the table. Just not too much of them (if not in mood to hear ghostly complaints about having zero self-control and eating too much lemon waffles again).

I want to just appear in unsupervised boxes, like a cat

I will appear when people don't turn down or off the bright lights after 930. People will be hella confused as to why the dark rooms aren't haunted.

I would appear after somebody took enough benadryl.

Ginger peach tea and a paperback book also at midnight though. I roll up as pissed off as Samuel getting summoned by the witch of endor but after I'm released the label printer will work and all the patients will go to bed.

I would large it if my eternal slumber was interrupted by stupid people asking stupid questions.

I kind of get hauntings now, I'd be vicious as hell and taking it out on people that deserve it.
