90's short cartoon about a vampire and his nightmares cartoon
I remember a short time toon I used to watch on the early 90's and now I forgot the name.
It was about a vampire that did something and he ends up dead. But all that it was only a nightmare! When he dies in his dream, he wakes up and then goes back to sleep, closing his cofin.
The toon must be very short in time. Maybe under two minutes.
I really want to know the name of it and find some pictures. Please, please help me. Or even guide me where and how to find it
