Yes. Feeling detached or unreal after a tough trip is common and often eases within a day or two. Treat this as recovery time: rest, hydrate, eat something hearty, and skip caffeine or nicotine for now.
Use simple grounding: name 5-4-3-2-1 things you can see, feel, hear, smell, and taste; splash cold water on your face or hold an ice cube; place firm pressure on your body with a blanket and breathe slowly while describing your surroundings out loud. Get outside for a gentle walk, look at the horizon, limit scrolling, and aim for an early, regular bedtime.
If the dissociation feels unmanageable, lasts more than a week, or your safety is a concern, reach out to a trusted person or a professional. For a short, step-by-step grounding plan, see this overview on dissociation after a fear-filled trip.
Be gentle with yourself. This can pass.
