What does looking for someone in a dream mean?

My dream was we were at some big place with all these games and it was someone's birthday. I assume it was an arcade but it had rooms just for whatever game you were playing. I went in with 2 friends (I have no idea who they were.) and we had old tracfones no IPhones. And we were wearing things from early 2000s. It's like we went back in time. My mom was there for the birthday but everybody got up and left us 3. So we were frantically looking for my mom because we couldn't get home without her. Eventually the place was starting to close and 1 of the girls were lost. So we were looking for the youngest girl and my mom. And we were really scared. We told people we couldn't find our mom but they just laughed. Why?
I woke up right after they shut the lights off for closing time. What does this dream mean?

See mother in dream has good meaning, it is kindness and sucess, maybe you will find a girl who you will love or a problem in your life will solve soon:-)
