This spell will help bring nightmares to another person. The supplies are:

One black candle

Dried mugwort

Dragon's blood (a resin incense)

Charcoal tablet

Heat-proof dish or tile

A large piece of white paper or fabric

Black marker

On the paper or material, drawn 3 concentric circles and an x in the middle of the smallest inside circle. Place the dish with a charcoal tablet right on the x, and the candle outside the circles on the left. Light the charcoal and get it burning, put a pinch or two of dried mugwort on it along with a chunk of Dragon's blood. When they are both smoking nicely, light the black candle.

Watch the smoke rising from the dish and picture it floating through space to your intended target. It brings nightmares and fear into their sleep, so picture that scene for several minutes and focus on the person. Repeat their name in your head as you do.

After a few minutes of this concentration, put out the charcoal and switch the dish and candle so the candle is on the x in the center. Leave it until it fully burns down. The person you're targeting will have bad dreams and nightmares starting the next night and it will last for 3 days.
