Undoubtedly, I have heard this zillions of times since my childhood.
get lost - used to tell someone forcefully and quite rudely to go away
Now, look at this campaign sentence -
The soothing music of subliminal language takes you to the eternal journey of your soul. It's mind refreshing and rejuvenating. You get lost into the world of serenity and divineness.
Get lost... huh? I literally mean that you really lose yourself into the world...
Is it proper to use get lost there? Still, I want other alternative that should mean one loses themselves into that world.
