Every now & then I have this recurring dream

It always has to do with me and mother staying in a hotel. Somehow we gets separated and I have to go find her. I never remember what gets us separated. And I always explore every floor of the hotel before looking for her outside. And the outside looks different every time, while the hotel is always the same. I’ve had dream three times within the past couple of months. I have no idea what it means. And I don’t remember every finding my mother. And floor of the hotel seemed to be empty, except for the lobby. I kept hearing my mom’s voice in my head as if she was close by, but she wasn’t. This dream is weird as hell. I only wish I knew why I keep having it.
