The whole idea of subliminal suggestions is not paying attention to them – otherwise, they would not be “subliminal”. You just run them as background music, or music for sleeping. You are not supposed to hear the text at all.
If you are listening to positive suggestions on a recording where you hear the words – this is either hypnosis or suggestions while awake, you can also read affirmations aloud or in your mind – but subliminals are the whole other method when suggestions go straight into the subconscious mind as you do not see or hear them consciously.
Just relax and let it happen. Let the subliminals do the work. Feel good knowing it is on its way. Actually, it is already here, you just are not on the same vibrations as your desire. When you are ready for it, it will appear.
