dendrobium nobile with a new growth?

[BD11]

So I stopped watering my Dendrobium Nobile around October 1st because it lost almost all its leaves so I figured time for its winter rest.

I took a good look at it yesterday and low and behold it has a new growth. I am confused because I would have thought it was going into dormancy. I went ahead and watered it again but I am not sure what it is doing at the moment.

Also it did have some spider mites on it a few months ago which I am pretty sure are all gone now but would that have any affect on its going into dormancy?

Thanks
