Introverts will become reserved and guarded around people whose energy doesn’t feel “safe.” Because many introverts can pick up on the energy of others. They can feel a person’s vibes and intentions. I used to not like that about myself, that I could sense and feel a person’s energy. But now I see it as a gift. Because I know when I need to protect myself. And I know when I’m in the presence of someone who I can’t trust, or open up my heart to.
