These are sometimes the signs that reflect their effect on our decisions in a particular situation. To be honest about it not many of us seriously think about things like intuitions, vibes, and energies. As many people live there in a certain way where they let things go by their own flow or they create that flow on their own and these things by which people create their own flow are mostly affected by their intuitions and experience.
And then in the end to support these decisions with a solid view we all rely on our experiences, which can be our personal ones or experiences shared by others. Then again it takes a lot to gain personal experience, as you've to go through different phases of life and have to suffer in pain to see a little rain.
Then after when you've been through a lot or sometimes when you get to know about things in certain ways that enlighten you about things that affect life then after that you always try to take decision by keeping your intuitions and past experiences in consideration. Similarly when our elders says like we know more than you they might not know the present scenarios of the world but they got a lot of life experience by which they always try to guide us.
So at the end I just want to end by saying that, life is all about learning and experiences. It doesn't matter what kind of place you're in in what situation you're in you'll always get to know new things about life that will inculcate your intuitions and help you in your future.
So never stop thinking and observing your surroundings, you don't know what you might get to experience.
