🌌 Existential OCD: When Your Obsessions Are About Reality, Meaning and Existence
What if nothing is real? What's the point of anything? What happens after death? Everyone wonders. With existential OCD, you can't stop, and the questions start to take over your life.
8 min read · November 2026
Most people have lain awake wondering what happens after death, or whether life has a purpose. Usually the thought passes and life goes on.
For people with existential OCD, it doesn't pass. The question lands, and with it a wave of dread. You have to figure it out. You read philosophy, physics and religion. You analyze, debate and test how real everything feels. Hours turn into weeks. The more you think, the more unreal everything starts to seem.
What is existential OCD?
The International OCD Foundation describes existential OCD as intrusive, repetitive thinking about questions that can't be answered, which may be philosophical, frightening or both. The questions usually involve the meaning, purpose or reality of life, the existence of the universe, or one's own existence.
Common existential obsessions include:
- "What if nothing is real, or I'm in a simulation?"
- "What's the point of anything if we all die?"
- "What happens after death, and what if it's nothing?"
- "Do I really exist? Am I really me?"
- "What if free will isn't real?"
- "What if I'm the only conscious person?"
Many people can read about these topics or sit in a philosophy class and then move on. People with existential OCD can't drop the questions.
Existential OCD vs. an existential crisis
- An existential crisis is usually triggered by a life event, like a loss, a milestone or a big change, and resolves as the person finds new meaning.
- Depressive thinking dwells on hopelessness and the sense that life is meaningless.
- Existential OCD is driven by doubt and the need for certainty. The questions feel urgent, intrusive and impossible to put down, and they come with compulsions.
They can overlap, and existential OCD sometimes comes with feelings of unreality (derealization). If you're having thoughts that life isn't worth living, please reach out for support right away: call or text 988 in the US.
The compulsions in existential OCD
- Rumination: thinking through the question again and again to find an answer
- Research: reading philosophy, science or religious texts for certainty
- Reassurance-seeking: asking others whether they ever wonder about it, or what they believe
- Checking: testing whether things feel real, or monitoring your sense of self
- Avoidance: steering clear of movies, conversations or topics that trigger the questions
As the IOCDF puts it, obsessive doubts can't be argued with or reasoned out, and there are never lasting answers to obsessive questions. Trying harder only feeds the loop. See OCD rumination.
How ERP treats existential OCD
ERP doesn't try to answer the big questions. It helps you stop needing an answer. With a trained therapist, you might:
- Face the questions on purpose, for example by writing or listening to them, without trying to solve them
- Resist the urge to research, debate or check how real things feel
- Practice uncertainty: "Maybe I'll never know, and I can still enjoy this coffee, this conversation, this day"
- Re-engage with life, focusing on what you value rather than what you can prove
