If, years later, I do use the slit detector to observe which way the electron went, it will mean that many years earlier the electron must have passed through one slit or the other. But if I don't use the "slit detector," then the electron must have passed through both slits. This is, of course, extremely weird. My actions at the beginning of the twenty-first century can change what happened thousands of years ago when the electron began its journey. It seems that just as there are multiple futures, there are also multiple pasts, and my acts of observation in the present can decide what happened in the past. As much as it challenges any hope of ever really knowing the future, quantum physics asks whether I can ever really know the past. It seems that the past is also in a superposition of possibilities that crystallize only once they are observed.

Love blurs your vision; but after it recedes, you can see more clearly than ever. It's like the tide going out, revealing whatever's been thrown away and sunk: broken bottles, old gloves, rusting pop cans, nibbled fishbodies, bones. This is the kind of thing you see if you sit in the darkness with open eyes, not knowing the future. The ruin you've made.

Margaret Atwood, Cat's Eye

Become a good noticer. Pay attention to the feelings, hunches, and intuitions that flood your life each day. If you do, you will see that premonitions are not rare, but a natural part of our lives.
