In search of particular spell book that I used when I was younger.

When I was about 13 years old, my friend Sabrina, who had just moved to the US from Ireland, came to my house for a sleep over with a spell book. I have always been extremely intuitive, and was very intrigued.

We performed a spell where we cut out 26 cardboard squares, wrote the letters of the alphabet on the squares, turned them upside in a body of water under the moonlight, said my chant, and when I woke up, two letters were right size up; R and L. These are apparently the initials of my soulmate.

Has anyone heard of a spell like this? I have been searching for years for the source of this spell or book since I had such an amazing connection with it. It's literally stuck with me 17 years later. I haven't been in contact with Sabrina since 7th grade. Any help is appreciated!
