"The Growlers' song What It Is" explores themes of belief, the supernatural, and the uncertainty of life and death. The lyrics suggest that people often dismiss or discredit the existence of the spiritual realm until they personally experience something unexplainable, such as encountering a ghost. The song implies that things are not always what they seem, and it is easy to dismiss the paranormal until one's own eyes witness it. The songwriter, who claims to have no specific faith or knowledge of the afterlife, acknowledges that he cannot deny the possibility that the dead do not always completely disappear. He recounts a personal encounter with a ghost, which he describes as being as clear as the numerous drinks he has consumed. The experience challenges his previous skepticism towards tales of fear and the existence of supernatural entities. Despite not subscribing to any particular belief system, the songwriter recognizes the value of life and encourages others to make the most of their time alive. The lyrics suggest that by embracing and appreciating life, individuals can potentially achieve a form of eternal life. The song touches upon the idea that life and death are interconnected, and death should not be feared but seen as an opportunity to seize the present moment.
