In my opinion ghosts are the same thing I saw above only the physical body of a ghost has passed over and is dead. I have had many dealings with ghosts and most of them, though a little scary and a little thrilling, were good for the most part. I did find a great site for ghosts stories . . . Onto a little more tropical beings . . . They're cute, but not THAT cute.
People are in love with mermaids as they have been for centuries.
Something about them is so alluring and curious and they have this spellbinding way, or at least that is how they are depicted often. I have always wanted to see a mermaid, they must be beautiful, but the only person I have known to see anything even similar is one of my friends. She saw them in the ocean but they weren't as large as a mermaid might be. Though, I can't help people get into contact with mermaids, I can help people get into contact with ghosts, one of my favorite types of visitors . . . For me what works is whatever stirs up energy.
