Some really good stuff here- excellently shot and a clear handle on the basics of the genre.
However, the story left something to be desired, I think we saw a lot of Tech Thrillers this year which dealt with very similar ideas, and I don't feel that this one popped. You kind of know exactly where it's going after that first scene, and while Tech Thrillers do lend themselves to this kind of thing, I would encourage you guys to try figure out something more original next year. I also wasn't exactly clear on the science of the ending- how did the VR girl become a physical entity in the real world?
The transitions from VR to RL was really well done, but I do wish we had some more exciting imagery than just this house to accommodate such effective cinematography.
As for your title, I'm not really sure how "Hysteria" plays into the plot in any specific way.
