*I must remind you that love spells can be very powerful, as well as dangerous, so take caution when messing with someone's mind and emotions. A spell like this may turn out to have negative effects on the 'victim' or even yourself. It is also very possible that you do not truly want the outcome, and are being led by desire and overlooking all the negative details you'd rather not see or acknowledge. If you feel doubt of any kind, do not cast a love spell. It's better to be safe than sorry.
Burn a red or pink candle in your (dark) bedroom at night, before you go to sleep, while envisioning yourself with the one you love. Say these or similar words:
I am love
Love is me
I'm the one you want to see
Think of me
Dream of me
Long for me
So mote it be
Repeat until you feel sure the spell has worked. Snuff out the candle, climb into bed, and imagine this person next to you as you drift off to sleep.
