Retreats can genuinely be booked standalone, with no medical procedure attached - that part is real. What wasn't real was this specific static booking, its price, and its day-by-day plan, shown with no actual patient or retreat behind them.
This page also showed a fabricated 8-day trip timeline for the removed fake booking. A real, day-by-day itinerary is generated automatically once a real booking is confirmed, and appears on your dashboard.
