When I die

I'll hire a shady looking man dressed in a hat and trench coat at my funeral. He'd be at a distance where it wouldn't look obvious he was at the funeral, but also within distance for some people to notice he was there. If I wanted to take it one step further I could get a custom made mask of my own face and have him wear it, so that the people who notice him question whether it's me or not.
He'd leave shortly before the funeral was over to avoid interactions with anyone else. His whole purpose would just be to stand there and make it seem like I actually got up to something important and/or intriguing.

Another thing I could do is hire a bunch of people to also wear masks of my face, and sometime after my death, have them go out and cause chaos, breaking into people's house in the middle of the night. They wouldn't hurt anyone, but the idea is to make it seem like I'm haunting people.

I could also do this thing where when everyone arrives at my funeral, everyone is shocked to see that the casket is empty, and a guy comes out, closes it over, and then taps on it with a wand. When he opens it my dead body is in there and everyone claps.

I could also hire a look alike to lie down in my casket and then when people start to approach it, have them get up and start screaming and jump out the window. Everyone is absolutely terrified and then it's revealed it was all just a bit.

I could also make a load of recordings that people discover when I'm dead. They get people to go down some sort of rabbit hole I made up which leads to something dumb like a picture of me sticking my tongue out.
