# possibilities.: The airy and spaced out feeling is concerning. The possibilities would includema drug effect, or something that is causing changes in your brain. Pressure in your chest and some nausea could be symptoms of a heart problem. The air bubble sensation may mean some acid is being refluxed from your stomachs to your esophagus. See your primary care physician.
