Meditation in this regard is similar to the wildly successful TV show, Seinfeld, a show about nothing! To expect weightlessness, levitation, rapture, enlightenment or bliss from your meditation practice defies the core idea underlying the practice; Vairagya or complete non-attachment towards worldly desires as highlighted by Acharya Pattanjali 3000 years ago. He took this idea even further by talking about Para Vairagya, non-attachment even for holy and auspicious goals such as spiritual enlightenment or oneness with the Almighty.
When you pleasantly focus on your breathing, or on a mantra, you will hear noises both external and internal. You for sure will have intruding thoughts about worldly affairs, your desires and challenges. And this is where Vairagya comes to the rescue. You practice total and complete non-attachment to them. You observe them and let them go while pleasantly bringing your focus back to your breathing. This is central to the practice of meditation.
Starting your meditation session with expectations violates the core principle underlying the practice of meditation. So, shed off your expectations, sit comfortably, close your eyes, pleasantly focus on your breathing and detach yourself completely from your thoughts, desires, ambitions, and goals.
Keep it simple and just meditate.
