My wife is having trouble sleeping because she can't stop hearing the guide's voice.

My wife uses guided sleep meditation, but now she wakes up in the middle of the night and can't go back to sleep because she is mentally replaying the guide's instructions. She can't switch the voice off. Her husband is concerned that the audio guidance has created an auditory fixation that is spiking her overthinking and causing chronic sleep disturbance. Is the solution to switch to instrumental music instead? Name: Anjali. DOB: 5th September 1989. Time: 11:05 PM. Location: Bangalore.
