Is there a ''ghost in a bottle'' on eBay?

People on eBay do sell "ghosts in bottles." Although these are most likely all fake, it is possible to "trap" an entity in a bottle through a process called binding. Not for the inexperienced, binding is a very serious practice requiring experience. Also, the binding will not last indefinitely, and when the spirit is released, it is likely to be pissed at whomever trapped it. It could very well seek revenge, and could possibly take that revenge in the person's future lives.
