The Barnum Effect

You see personal specifics in vague statements by filling in the gaps.

Because our minds are given to making connections, it’s easy for usto take nebulous statements and find ways to interpret them so that they seem specific and personal. The combination of our egos wanting validation with our strong inclination to see patterns and connections means that when someone is telling us a story about ourselves, we look to find the signal and ignore all the noise.

Psychics, astrologers and others use this bias to make it seem like they’re telling you something relevant. Consider how things might be interpreted to apply to anyone, not just you.
