Elevator operator tells scary stories, ends up trapped in the mirror [closed]

Could this be the German TV movie "Geisterstunde - Fahrstuhl ins Jenseits" from 1997?

Rolf Hoppe was the elevator operator, he is white haired, but he is not black. (He is wearing a black tuxedo, that might have mislead your memory?)

Here is the plot summary from an IMDb-user:

A night watchman tells three extraordinary stories to a journalist and a producer, trapped with him in a lift. Embedded in a single story, three tales develop some interesting themes, notably that of a double persecutor. Some good actors for some harrowing moments.

(highlights by me)

Here are some pictures from that movie, they might ring a bell.

I only remember the old man, but what I've read on some German pages, the 3 stories are about:

1. A 17 year old girl meets another girl while sleepwalking. Later it turns out that this other girl lived in the same house, but was killed 33 years ago.

2. A female painter moves into a new flat and hears a man tyrannising his family.

3. An unsuccessful comic-strip artist, who creates a successful twin using a magical mirror.
