This thing is probably cursed. Read at your own risk.
This ritual is very dangerous (possibly one of the most dangerous, along with Living Doll Game), so make sure you remember the instructions perfectly if you ever decide to try it. If after reading this instruction you begin to feel a sudden drop in temperature or your shoulders getting heavy, you must not try it at all
1. After Midnight (around 2 or 3 am), before you go to sleep, lie down and look at the four corners of the ceiling one by one, slowly and anti-clockwise, starting fromt he corner that is closest to the North.
2. You must do it three times. Slowly, and anti-clockwise.
3. Then cross your arms on your chest and chant "On-beiro-kya-mashironi-sowaka" three times.
4. Still keeping your arms crossed, imagine a long and black haired woman in a white kimono, covered in blood and with her hair down, slowly coming closer to you.
5. When she arrives in front of you, stop imagining
6. Uncross your arms, turn off all lights to leave the room as dark as possible, and go to sleep.
7. You will see a woman in white kimono covered in blood in your dreams.
WARNING
Even if the woman comes close to you, you must not speak to her.
She might ask for your name, but you must no tell her.
If she starts muttering something into your right ear, shake her off by waving your right hand. That should wake you up.
If after you have woken up, you look around and see no black shadow of the woman lurking in any of the four corners of your room, then you are safe.
Trivia:
The chant you recite to summon her sounds like a mantra of Shingon Buddhism (Read more: Shingon Buddhism)
Good luck!
