To dream of a walking stick should be seen as a warning. You are making rash decisions in your waking life and over-committing yourself.
If you are using a walking to stick to move, you may want to consider how much you rely on those around you for advice. Are you taking advantage of a friendship?
If you dream of a bottomless pit, you are feeling hopelessness and despair in your waking life. The bottomless pit may be indirectly referring to your conclusion and acceptance that an issue has overcome you and is never-ending.
Dreaming that you are taking a Breathalyzer test represents guilt that stems from a bad decision. You were likely not caught or confronted about your poor judgement, but subconsciously you know that you could have been caught and it could have turned out much worse.
