Before I answer I would like to ask.

Do you have any feelings of uncertainty at your workplace or school/university?

Not necessarily negative although that could be. It could also be positive such as anticipation of a new promotion or raise perhaps? Upcoming exam?

Any concerns about work/school?

Starting a new job or school? Moving to a new location?

As far as your dream it does sound like you were maybe mildly lucid and with a possible false awakening. Look for recurring themes with your dreams and record them.

Lucid dreaming has different levels of awareness. You will definitely know if you have a full blown LD. Once you have done that (and you will if dedicated) then it becomes easier to spot the less lucid (yet still lucid) dream experience.
