It's generally referred to as day dreaming when people do step into their 'imagination devices'. Personally I do that quite a lot, especially in dead moments like on the bus. I find it to be more entertaining than using a mobile phone with terrible internet. Though, it's probably not amazing as you might imagine. For most people, visually imagining things isn't as vivid as real life, it lacks detail, and there aren't really any surprises in what you imagine. But most of all, if you're used to this 'power', it just feels mundane. Someone who can't walk might assume that walking is an amazingly pleasurable experience, but for someone who walks every day, it doesn't particularly feel very special.

And indeed, the contents of what I imagine are rarely something I talk about. It feels private, and like dreams, it's hard to convey the experience to others. You might also not recognize it if I do share something about my daydreams. Suppose I said: 'I was thinking of going to the beach', then you might assume I was thinking more along the lines of your typical thought experiences, while I was actively visualizing said beach.
