Dream About Stolen Toothbrush And Getting Lost

Last night, I dreamt my nursery I work in got merged into a different building. It was absolutely massive that you could easily get lost in it I was working in one of the rooms when I heard one of the work girls say loudly downstairs 'Steph won't care if I take hers, not like she would notice'. Everyone heard her and thought she was taking me for a fool. I got annoyed and decided to investigate I then saw her down at the bottom of the stairs with my toothbrush and she said to me 'do you mind me taking this?'. I responded sadly saying 'no of course not' I then went to my manager to tell them how annoyed I was that this girl stole my toothbrush. They all just laughed at me and then I got lost trying to find my way back to my room.
