A spiritual attack dream

Had a weird dream that believe it to be some kind of spiritual attack. Here how it goes, I was in a school listening to some army talk about introducing sea defence. After the talk, I was around and see some of my old classmates and pretty ladies, I happened to bump into a 40 - 50 plus lady what was walking down some tall staires, I lend her a hand and after that she told me dun bother helping her as I can use that time to talk to those pretty ladies in the school. After helping, I went to the crowd and saw many adults, so i believe it was suppose to be a fair now. Saw a few pretty ladies but just walk pass them, dun have much interest after all. I feel a urge to release myself, so I went to look for a toilet. Walk for a while, saw students playing outside the balcony, westle here and there. I finally manage to find a gents washroom, went inside and saw a little girl playing with the water inside the urinal, got abit freakout and turnoff, went out of toilet and to find another toilet. A male cleaner walk pass me as a apporach the doorway of the washroom, told me: "Do u see what i see?" Then I feel something must be strange about it, at that time I was at the corridor le. I look back and the little girl in long black hair and with a red dress came out. I stumbled for a moment and walk towards her and grab her hand, she stare at me, then I stare at her back. I can feel that she want to possess me as I can feel weak and numb in my body, struggle for a while and I happen to look at another little girl that bought to this place by her parents. I began to think that such thing (what if the spirit possess that little gal) CANNOT happen to her, force myself to look back at the spirit. Then spirit suddenly become smaller and I use my right palm, put over the spirit head. I say: "I cast u to hell", the spirit vanish, a puff of smoke come out of my fight palm after that, majiam I extinguished that spirit. After that I wake up le. I feel goosebump all over, I pray to God the moment I walk up. Now still got goosebump but feel great, cause I can feel that God is with me.
