nonsense, or do they have some pseudo-scientific basis to them?
How do people know if they’re psychic or not? What are some signs that someone might be gifted in this way?

Determining whether someone is psychic or not requires an understanding of the person’s specific situation and experiences. However, some signs that someone might possess psychic ability include: dreams with strong visions, premonitions of events before they happen, having unusually heightened senses such as hearing or feeling things other people don’t, having a strong connection to animals or nature, and having unexplained knowledge about distant places or events. People may also become aware of their psychic abilities when certain memories come to mind before another person speaks or when the person feels energy in the form of heat or electricity. Additionally, people who experience this gift often develop extra sensory awareness regarding objects that have no immediate connection to them.

One way to tell if someone is psychic is to observe how often they have flashes of insight or intuition about things. They might also dream about events or people, and pay attention to any recurring symbols that come up. Other signs could include being able to sense the energies or emotions of others, a strong connection with animals, plants, or nature in general, and having vivid visions when meditating.
