Rose Revenge Nightmare

Draw an pentagram on the floor. Place the two pink candles on the floor (left, and the right.) Place the two red candles (top, and bottom.) Place the black candle in the middle. Sprinkle the rose petals around the pentagram. Light the candles. Place the rose next to the black candle, place it over the black candle. Carefully pour the blood over the rose, while doing that say this spell; "Goddesses of darkness, nightmare, and revenge, please hear my plea. Touch the rose with your powers, make the thorns poison to the touch, please, make it so that if one touches the thorn in a dream, then they will be in endless sleep, not age, nor die, only sleep."
Ship or place the rose on the front door, of your victim. Make sure that it has a note, (they have to put the rose under the pillow for it to work.) You have three days for the spell to work, if not then find another way.
