Halloween is a time when it’s fun to wear disguises and pretend to be someone else. But there are real monsters disguised as caring humans, and psychologists designate these individuals as psychopaths. If you get involved with them, it can be devastating. One of their favorite ways to manipulate you is a series of psychological ploys collectively known as “Gaslighting.” Here are six signs someone may not be whom they seem to be:

1. Lying is second nature. They will lie, when the truth will serve just as well. This is intended to make you doubt your reality. If you call them on their conflicting versions of of events, they’ll say your memory is faulty. Or that you’re the one who’s lying. This is a definite red flag!

2. Blatant discrepancy between words and actions. The person may say they care about you, but their actions say otherwise. They may say they are looking for a job, but remain unemployed for months. They might claim to have lots of friends, but you never meet them. Maybe it’s time to wonder if they are being completely honest.

3. Projection. You know they lie, but they accuse you of lying. You catch them cheating, but they accuse you of cheating. Their actions are irrational, but they say you are the one who’s crazy. Pause and do a reality check. What are the facts? It can be hard to tell with these people.

4. Separating you from support. They will separate you from family and friends. Without your support group, you’re more likely to succumb to their tactics. Don’t let this happen!

5. Denial. They will deny everything. If you catch them lying, cheating, or stealing, they’ll deny it. Sometimes you’ll begin to doubt yourself. Ask around. If they’re doing it to you, they’ve probably done it to others.

6. Flattery and contempt cycling. They’ll flatter and love you, then tear down your self-esteem. Then they’ll apologize and flatter you again, only to start the cycle all over. This is an insidious form of abuse that is so damaging, it often takes years to recover from it. If you see this happening, don’t excuse it–walk away from it.

Beware of these predators masquerading as caring humans. There are no treats here, only tricks. Have a happy and safe Halloween!
