The concept of 'Sleeping with Gaga' is not so difficult to understand. Just remember that it was happening during her perfume titled 'Fame' launch event. And the perfume is meant to show the dark side of fame (the colour of the perfume itself) but it also represents the seductive side of fame (it's scent). Gaga showed us the dark and seductive side of the fame during that performance.
She was sleeping like any other human being, but her fans still watched it. They also were able to touch her hand while she was sleeping. Now, would you disturb a person who is sleeping? No. But they still did and watched the video of her sleeping, peeing and so on which means that the whole world is crazy about celebrities. They want to know every detail of their life no matter what it takes, which is sometimes hard for celebrities to deal with. This is the dark side of fame.
15 minutes on the clock is also an important detail. Andy Warhol is the author of the saying ’15 minutes of fame’. You all know what it means. No need to explain. So it’s like while Gaga was sleeping, everyone was waiting for those 15 minutes to end and witness what will happen next. It’s the nature of fame ‘They build you up to tear you down’. Fame in pop culture is very fast and fragile. Everyone is waiting for next big thing and their 15 minutes in order to later forget them.
Gaga getting a tattoo during the performance is also symbolic. We all know that getting a tattoo is painful. And everyone watched her getting one and enjoyed it despite the fact that Gaga was in pain. The world enjoys seeing celebrities to suffer in real life. Tabloids love scandals and so on. It symbolises the dark side of fame too.
The seductive part of the fame is that no matter how humane those celebrities are or how much they suffer, the world loves to see it all. Also, many people want to be famous despite the dark side of the fame itself.
There are many more details, like her being in a fame bottle, like a caged animal in a zoo and so on..
Everything makes sense. It’s a brilliant performance.
Sorry for my English, but I hope you get what I mean.
