AwareBeing...thank you for responding. I had a look at the first link you posted to see if it answered the question. And it sort of did. Sort of Your explanation really seemed to address 'entities' attracted or repelled BY the vibration. So it didn't really help me understand WHAT it was.
This was what the first link said...so I'm still not quite understanding. It seems to be something, maybe an energy of some sort (maybe electrical? just guessing) emmitted by emotion. Is that correct?

Measuring Thought Vibration is a method new-age folk use to determine whether a thought you are thinking is empowering or disempowering. If you practice thinking thoughts that have a higher vibration, you tend to get more of what you want in life – and you feel better about yourself too.
Essentially, thoughts that vibrate at a higher level are likely to be strong, positive and healthy thoughts, whereas thoughts that vibrate at a low level are liable to be negative, harmful and disempowering.
The argument is what you think about most you manifest in your life – so if you’re operating from a higher frequency, you are more likely to attract the life you desire. You’re also likely to be happier, more pleasant to be around, and in a better state of mind.
This article will explain a bit about high and low levels of thought vibration, explain the benefits of vibrating at a higher frequency, and show you how to turn low frequency thoughts into high frequency thoughts.
