In last few days i was doing a lot of FRTRs (3-4 in one night.). I did FRTR + Tetra + Shattering in all FRTRs and i had minimum 15minutes of break between rituals. One night i had nightmares. Than last night i did 3 FRTRs and went to bed, and than i was hearing voices like that the TV is turning on but it was off. When i almost fell in sleep i heard it again and became awake. Than again i almost feel asleep and the voice heard again. It took about 2hours to sleep. Im afraid that will happen every time i will do FRTRs. Is it possible i have spirits in my room? Should i do banishment ritual or what?
