Written by Billie Eilish with her brother Finneas, this was inspired by a nightmare the singer had one night. In her dream, Eilish killed herself by jumping off the Golden Gate Bridge only to witness her friends, work colleagues and fans ignore her demise. She woke up with the feeling that despite achieving "everything I wanted," some still see her as disposable. Eilish turned to Finneas for support; he comforted his little sister, saying she should "change the way that you see yourself" and "they don't deserve you."

I had a dream I got everything I wanted But when I wake up, I see You with me The heartfelt song showcases Billie's strong bond with Finneas; her brother has been a steady source of support and encouragement throughout the teenage singer's life. She explained to BBC Radio 1's Annie Mac: "The message behind the song is like my brother is my best friend, and I have these dreams and these things happen, and no matter what happens, he's gonna always be there for me, and it's the same the other way around."

Billie Eilish wrote the woozy song with Finneas at their home studio in Highland Park, California, and on tour. Finneas also took care of the production and sang the backing vocals.
