Your stress levels can affect your ability to LD, for sure. It's not necessarily the change in surroundings - I still have dreams about all the places I've lived - as it is about your reaction to those changes.

Keep a dream journal, even if it's just in a notebook, and keep RCing. Give it time, get comfortable in your surroundings, and you'll get the hang of it again.

You might want to consider meditating, as well.
