What is the point of having them if we can't interpret their significance before it emerges in our lives?
Well, one thing I've accepted is that sometimes we won't understand their "point" or purpose "in time." That is no one's fault. It doesn't mean we "failed" or failed to protect ourselves. Sometimes, a lot of the time, it won't be possible to figure out what our intuition is telling us before that event takes place.
I do understand where you are coming from, though. I had a strong intuitive hit about car accidents right before I was in my only car accident in 2003. To this day, I still sometimes regret not trying to pay more attention to it, figure out what it meant, etc. Even though one reason I couldn't do that then is because I was still about 100% skeptical about "psychic activity."
Also, over time, I had to accept that sometimes intuitive flashes just...happen. It can't be controlled, it happened because I was sensitive that day. And it gives one unwanted information. You got a premonition about Dolly Parton. This has happened to me more times than I can count. It's unnerving. Michael Jackson would be the most uncomfortable example. I didn't like him, but I didn't want to know he was about to pass, either. Also--I sometimes get hits about celebrities' energy problems (and other problems) while watching t.v. or film work they have done. This has wrecked a couple of fanships for me. (David Duchovny has horrifying energy, and after picking up on it in 2007, I was unable to watch anymore reruns of The X-Files.)
I can't really offer any advice except that over time I have just learned to go with the flow. Every once in a while, paying attention to my intuition helps me avoid something bad. Or helps me attain something positive. Most of the time it doesn't. Accepting this is just part of the challenge of living with sensitivity.
