In my experience There is nothing to be afraid of. They have me spray the treatment in each nostril 3 times at 5 minutes apart so it is gradual. I am in my own room in a super comfortable chair. I cover my eyes with a scarf and I listen to my playlists. You do feel disconnected from your body which feels like an incredible relief! Some people read or have a computer with them, and I have no idea how they are able to read or work! Different for different people. Nothing scary or threatening
