When recognizing other vampires, I've found that the way in which I recognize others can vary from vampire to vampire. Sometimes there is sharp punch in my heart chakra that makes me aware of another presence and sometimes there's a deep connection that is just "Known" merely from gazing into their eyes, and it's very subtle and unspoken between us.
Does anyone else have any vampire to vampire recognition stories they would like to share?

I resonate with the experience of flavor. I find that other vampires tend to be "richer," somehow.

After my awakening, I really started to take note of other people's energies. Somehow what I felt from people seemed to best fit in the realm of Taste. Not usually flavors per se, but close.

In my own experience, I've found that vampiric people have an energy that feels or tastes richer than those who are non-vampiric. The quantity of energy in vampiric people is ever-shifting, and is often in more of an ebb than a flow. But I find that the quality tends to be quite rich, or dense. When I'm in contact with it, my own energy "ignites," almost as though to say "ah, I recognize you." Like a beacon, I suppose.

I would say more, but sleep calls.

Some people do refer to it as a "beacon" actually. An energy beacon that can be sensed by others.

For me it is a very distinctive feeling, a brief intense rush of energy.  Now I have been told by various friends that I have a tendency to glow at times, similar to a soft light that attacts things to me.
