i just finished watching the movie but I can't help it I'm soon confused . So the entity in the beginning was Clark ? , The mother has been the backrooms ? or she's a paranoid individual and she traumatized her child ? , I watched a movie ending explained and that didn't help so thought it be a good idea to ask here . It was interesting , great acting also very unsettling but I'm questioning what the place Is ? who are the docile beings ?(is the red head his wife really ? ), Why did the Clarke entity only attack him then ? , I have so many questions . I'd appreciate an explanation .....
