Dream about drinking straw is unfortunately a warning for harsh lessons that need to be learned. You are trying too hard to adapt to this new attitude. You are lacking something in your life. It is a symbol for your inability to overcome current difficulties. Your perspective is skewed and you are not seeing things clearly.
Drinking straw dream is a metaphor for someone who wants your full attention. You are turning a blind eye to certain things that would normally bother you. You are trapped in the past. Your dream is sadly an admonition for someone who may be looking for a relationship with you. You are trying to connect with someone, but it is not going anywhere.
If you dreamt about drinking straw:
You are always ready to try something (or someone) new. You find it easier to say “yes” than “no”. You are responsible for what you bring into your life and consequences are very real. Likewise, we are responsible to our bodies. What we eat is going to stick with us. You will feel what you let into your body for much longer than the time it takes to ingest it. Pay special attention to this process and learn the benefits of saying “no”.
