The song "Gaslight" by Scott Helman is about a person who is in denial and refuses to see the truth. The title refers to the term "gaslighting," which is a form of emotional manipulation where someone tries to make another person doubt their own perception of reality. The lyrics suggest that the person in question is ignoring warning signs and unable to see the danger they are in. There is a fire in the house, but they refuse to leave and believe that the smoke is just a harmless cloud. The song encourages the person to trust their own instincts and not be fooled by someone else's lies. The line "Only you can save you" emphasizes the need for self-awareness and taking responsibility for one's own life. The chorus repeats the question "Why can't you trust your own eyes? Why can't you see the gaslight?" as a plea for the person to wake up and see the truth. The bridge offers a glimmer of hope, with the suggestion of a way out and the invitation to "Come out the house now." Overall, the song is a warning against letting someone else control your perception of reality and a call to trust your own intuition.
