My mother is behaving strangely these days.. She tells us 1 that some people are using her spirit. 2.she tells us different people enter into us so she keeps asking us Who are you?? 3. She gets angry and starts using bad words. She stays alone in her room door closed. If we move things from one place to another.. She gets angry...we told her let's consult doctor.. But she says and argue s with us that we should see the doctor... Kindly advise what.. And what could be wrong with my mother. Thanks in advance.
