I usually use the word ‘immersive’ when I refer to water. Cool, refreshing, on a warm day, or a steaming-hot bath when it’s freezing outside. Completely immersing into water. That water can reduce your senses to the mere touch of your skin.
On the other hand, in the media immersion has an entirely different connotation. There is no water involved and all your senses are stimulated to their maximum potential. These two different types of immersion have one thing in common: you allow it to you take over. Anyone who ever spends an evening on the couch with a good book or an exciting film knows exactly what I am talking about. You forget the time, thirst and hunger, because you are completely immersed in the story.
