Dream #522

I have left my 13 y.o daughter at my work to pick up older daughter, without letting my 13 y.o know I am leaving her, when Ive picked up my older daughter Im panicked that I cant find my way back to where i left my 13 y.o...then I wake up fearing she is 'lost'...this is an ongoing theme in alot of my dreams about my 13 y.o just different scenarios I am losing her or I am looking for her and I cant get to her, these sorts of dreams have been happening for months now. Does anyone here have any idea as to what this might mean?
