What are “vibes”?
I think you can interchange the word “vibes” with “intuition”. They are basically the same thing. If you are interested in developing this gift further I would recommend “The Psychic Pathway” by Sonia Choquette. She has a number of other books too and they are all great for expanding your psychic horizons.
I think you answered you own question. 🙂 Vibes are just emotional feelings. “I didn’t get a good vibe from her.” That’s like saying, “I don’t think she was too receptive to what I was saying.” If you meet some new friends, it’s the same thing. “I didn’t get a vibe from that one girl.” Hope this helped.
