As for the one or two visits that Dracula makes to Mina's room...here I must confess to being pretty wool-headed.  I've read that portion of Gary's book, and I've read Clark's explanations on the board, and I've watched the 1931 film a zillion times, and Clark's revision at least 4 times...and I just can't make heads or tails of what anybody's saying about those scenes, what's in the script, what's in the film, what was or was not lifted from another scene.  I know I'm just so damn old, but it makes me dizzy to try to figure it all out.
If you watch my version, combining the Spanish footage with the Lugosi footage, I think it will be clear how the scene was shot and how it was edited down for the earlier scene.

I have a flash version that can be viewed online. It may not be wise legally, but I'm posting the link here just to make things easier.
