Preetiprincessji,
Last night suddenly I woke up and felt tremendous fear for unknown reason. I started chanting SAI NAM and lit the light. Then thought I am giving in to fear of unknown and why should I bother as BABA is with me. So I just said get lost and turned the light off to sleep. During that time you came in my mind and understood how fearful you might be. I have never ever come across with this sort of incident what you are going through neither I believe in this myself. But again how much we know about what is happening around us. I really felt for you. Also, I see Maa Kali as protective of HER child so why SHE will frighten HER own child I was questioning myself. By the way, many Tantriks, Sadhus, astrologers are very powerful I have heard. But isn't it true that SAI's devotee/child do not need any outsider force to be rescued? Do you really believe that SAI is with you? If so why are you going to tantrik? Rather you go to a temple of Kali if you think that Kali is with you. That means Kali requires your attention. It just a thought. Go to the temple of Kali if there is any near you and do the puja. Otherwise you find a picture of Kali mata and keep near you and chant her name and do the puja yourself. Request HER to leave you and bless you. Before you do anything ask for BABA's permission to guide you. MOTHER do not harm or frighten HER child.
Wish you all the best. Help yourself and stand up for yourself. Do not be victimised by anybody else does not matter if that's inside or outside.
Take care
