Lyric discussion by Eirinjas 

Cover art for The Rapture lyrics by Siouxsie and the Banshees

It's a song about an orgasm. When you orgasm only your senses remain; reality is momentarily distorted. You lose all thoughts and perceptions of time, place, and identity. This is why tantric meditation is a thing: the only waking state in which the ego can easily dissolve is in orgasm.
