A bigger issue is why his castle now looks so totally different and why you need to be a mountain climber to reach it. The previous film, a horse and cart just went up by the main road.
Or an even bigger question - when Dracula see's he is barred by the cross from entering, why not just have the priest now under his spell and who is clearly still human not remove it immediately, instead of going to another village to grab a girl to do it for him?
That's the least of that scenes problems. The thick ice cracks because a guy bushes it with his arm and then a trickle of blood just happens to run directly into Dracula's mouth reviving him and then a few minutes later Dracula's clothing is perfectly dry.
It's actually a very clumsy and badly staged scene that really makes no sense.
