This is the thing which happened with my buwa (aunt, father's sister) which I witnessed myself only. This is little bit lengthy but I'll try to keep it brief. I and my Buwa are more likely a friend and she tells everything to me and I tell everything to her.
My Buwa recently got married in May. The marriage took place in our native place i.e Uttarpradesh (Sultanpur). Our family lives in Mumbai. After the marriage, when she came to our house, her health was going down. She always complain pain inside her stomach, severe headache (feeling like someone hit her head) but my grandma said her to take medicine and rest as we have another wedding in our house. My grandma was so busy to even talk.
So my Buwa taken medicine but it didn't work at all and sometime she escape her meal. After the second wedding in my home, my buwa went to her Mausi's (her mom's sister) place in Amethi to just spend time with them. I was in my granny's place as we have little days to go back to Mumbai. One day I got call from her that she is admitted due to fever. I told to my dad and he rushed to Amethi. After the treatment she came back to home. I went to home one day before our train back to Mumbai. When I got to know what was the reason behind her heath degradation... What she told me was really shocked me.
The fever was not normal. Why I am saying this cause in thermometer temperature was nearly 105 Fahrenheit but she was not as serious as in this situation fever should have been reached to her brain. But it doesn't happen.
My Buwa told me that she regularly seen bad dream just before 6 to 7 months before her marriage. She seen in dreams that someone is breaking her chudis (Bangle- in Indian society it is a holy symbol of marriage). She saw this dream nearly four to five times. In another dream she saw that on the way to coming in temple she was beaten by a horrifying looking woman who was saying to her, "You will do puja. How can you do puja (holy rituals)?" and she was saved by another woman in saffron cloths. In another dreams she saw a person got his head cut by self and his body was drowning in river and he is watching with his separated head. She also feels in sleep like her bed was moving itself. She always awake after this and start murmuring the name of lords. All these weird dreams continuously suffered her before and after her marriage.
On the other side my Dad discussed this with one of his friend who is a tantrik (person who perform ghost rituals). After calculating, he told everything to my dad even the exact scene of dreams. (My dad didn't tell him anything about dreams and her experience.)
He told that the horrible looking woman was chudail (Lady Ghost) who was trying to possess body of Buwa. The lady in saffron was Devi (Goddess) who saved her. He also told him that she has this ghost back before 8 years from the roads. (People who removed their ghost always kept them in form of lemon on the roads). But ghost can't harm to Buwa due to presence of Devi (due to this she suddenly become vegetarian). He told that she must have been a feeling of that someone has hit her head. After listening this I recollect my memories and said that Buwa often told me, "I feel like someone hit my head through hands" but at that time we never listened her.
So now the point came if she had this ghost back 8 years so why suddenly she is showing her existence after marriage? In our village it is said that if someone has suffered from ghost and got married then the ghost also got married and never go from the body of victim and worsened the condition of victim.
Fortunately we were able to remove ghost from her body and now she is happily spending her marriage life. But this experience really changed her and our family's perception towards paranormal power.
