You can also immerse yourself in a book, a show, a game, a conversation, or a situation, which means you get very, very into it. When you're immersed in something like this, you're so interested, and so involved, that it's as if you're swimming in it. Sometimes I get so immersed in my writing that an hour flies by, but it feels like only a minute.
And if you're immersed in a conversation with your friend, you're deeply focused on it, as if you're swimming around in the words that you and your friend are saying. Your conversation is immersive, so the rest of the world goes away.
By the way, a great way to learn a new language is to immerse yourself in it. Immersion helps you learn fast because you jump right in: you talk to everybody in your new language, you watch shows in your new language, and you even start to think and dream in your new language. You're immersed in it.
