Dreamwalking

I'm not sure if this belongs in this group or not.  I just realized this year that I can help people with nightmares in the dream world.  I had a friend who was having nightmares daily.  I did some work, made an astral protection amulet with "holey stones" and a maroon ribbon and bound her dreams to mine.  Now she's been 9 months or so without nightmares every night.  She's had a few, but she said she can cound on one hand how many nightmares she has had since I bound our dreams.  Can anyone else do this?  Am I the only one?
