A plane crash is read as fear of a big ambition or hope coming down. Dream books link it to anxiety about failure or loss of control, and it is not understood as a forecast of any real event. Being on board is usually read as feeling carried by a plan you cannot steer, while watching a plane fall from the ground points to worry about a project or person you have invested in. Surviving the crash is read as resilience and a fresh start after a setback. It can help to notice which goal in your life currently feels too high or too fragile.
