But I cant close the door..

I dont think its to be near me, she carried it along the landing first...my room is the only other room open because of the door.

Why would she not wnat to stay in the other room?

She may not have felt safe there, thats the biggest reason for moving kittens.

Cats move their kittens for a variety of reasons.
They may feel unsafe - something has disturbed the mother cat, eg another cat, dog or person
They may not be warm enough - there could be a draught and the mother feels the kittens are getting cold
There may be too much going on around and she is being disturbed by constant movement or noise.
She may not like being in a room with the door closed even if she has everything she needs in there.
Trying to keep her where she doesn't want to be could be more stressful for her than allowing her to move the kittens to where she wants them.

In the wild it's common animals with vulnerable young to move them from time to time and create a new nest as predators could literally 'get wind' of an established nest. Some domestic cats remain hard wired to do this and it doesn't mean there's anything wrong but the instinct is so strong you won't stop them. It often happens when the kittens are around two weeks old.
