Does an entity have weight?

[Steven Wolff]

There have been experiments that suggest that when you "die" that 21 grams of weight disappears.

If Energy = Mass and ghosts are energy, then perhaps this explains the weight that a ghost has when walking on wood floors (Sounds of foot steps)?

What are your thoughts?

[parachick]

I have never before considered whether or not an entity would have weight. I have been on cases where we have experienced phantom footsteps and knocking in response to questions, etc. Upon reflection, this is a very plausible theory. There have even been times when footsteps are heard that a squeaky floorboard will be tread upon as well. That would have to take some weight I expect. This idea will certainly be with me the next time I experience this phenomenon.
