Short horror films

I went to a small screening of some short independent horror films recently some of the films include:

Mouse-X - This is a sci-fi dystopian film which cleverly uses the unknown as a way of creating fear in the audience. Some people may argue that this isn't necessarily a horror film and more of a sci-fi mystery but it does have elements of horror throughout.
Here is a short plot summery that I found on IMDB:
Mouse-X is a mystery/sci-fi story about Anderson, a man who wakes in a building with no idea where he is or how he got there, before slowly discovering that in each of the rooms around him are a thousand clones of himself, all of whom woke into the same mysterious scenario. To escape he needs to outwit his 'selves' whilst overcoming the realisation that he is not the only Anderson...

The Stomach - This film gives a twist to what people would expect to see in this kind of film. It may not strictly be a horror film but certainly shares many elements and is based on the ideas of horror.
Here is the lot summary given by IMDB:
Frank's had enough. A spirit medium whose unique and grotesque method of channelling the dead is putting his own life at risk, he wants out. But others, living and dead, have plans of their own. Part body-horror, part ghost-story, The Stomach is a unique tale of Supernatural Noir.
