When we sleep our brain decided which memory to keep and which memory to delete, nobody know's the process of this decision by our brain, but memories that are not interesting or important for us are deleted by simply dissolving connections between neurons, this happens during nREM sleep. So there is a limit of how much we can remember, I think because you moved to a new location, your mind is completely busy learning new things and you have very little left for your dreams. You are dreaming, but you mind decided that your new waking life memories are more important to store then your new dreams. As soon as you will get used to your new living, you will be having more dreams.
