live in a bubble

1. To remain physically or socially isolated from some threat. Because I have a compromised immune system, my mom basically wants to me to live in a bubble. I know you want to keep your kids safe from drinking and drugs, but it's not like they can live in a bubble.

2. To live life completely absorbed in or insulated by one's limited reality or life experience. The rich all live in a bubble of privilege—that's why they can't understand the plight of the poor in this country. Between his work and his video games, he has been living in a total bubble on his computer lately.

3. To ignore, avoid, or deny reality. Anyone who fails to see the hypocrisy of the governor's actions is living in a bubble.
