Unresolved negative emotions from the past can play a significant role in contributing to insomnia. Those unresolved negative emotions and limiting decisions from their past may be causing stress and can manifest as physical and psychological issues like insomnia.

In using NLP to deal with insomnia the core idea is to first clear any psychological baggage hindering sleep, then set empowering sleep goals, reframe limiting beliefs, and finally install new unconscious patterns and strategies to support those goals through the NLP processes.
