I'm glad a lot of people enjoy their hallucinations and that they are pleasant; no one deserves to be scared or threatened by their symptoms. I suffer from a variety of hallucinations including negative voices, music that can be creepy or classical music like the piano, and other sounds. If this hallucination does not progress into anything more serious and you enjoy it then it can be no cause to be alarmed.

On a side note, if you are experiencing olfactory (smell) hallucinations and hearing classical music you could be experiencing temporal lobe seizures. The neurologist I saw said that the classical music and smell hallucinations I experienced could be from seizures so I have a follow up in a couple of months for most likely another eeg.
