Her hallucinations and delusions could perhaps be schizophrenia symptoms.

Shes probably trying to mess with you or maybe she's worried about something. Talk to her about it and if she feels comfortable shell tell you . Good luck :)

First, there is no such thing as "crazy". People can have mental conditions that alter their perception of reality, but saying crazy is incorrect. That being said, no mental disease could ever be diagnosed with so little evidence. However the symptoms are indicative of Schizophrenia and similar conditions. The music piece I would throw out as I know many people that do this. If she said the music was coming from the walls then there could be room for more concern. The doors/windows being locked twice, while a bit paranoid in action, could be explained away as being raised to do so or she was jsut unsure if she had locked everything up. The cookie smell is a bit more disconcerting, as this means her senses are affected somehow. The most troubling bit it the shadow people comment. However, without professional diagnosis, which would take place over a series of interviews with a pyschiatrist (has a PhD and can actually prescribe meds), this conversation is pointless. Talk to her about your concerns, and if needed her family.
