Why do we have nightmares and crushes please help

A source of confusion or anxiety for most, nightmares may serve a very beneficial purpose, according to researchers.

Nightmares are helpful to our survival or else they probably would have been done away with by evolution, said Deirdre Barrett, a psychologist at Harvard University. Barrett theorizes that nightmares act as the brain's way of focusing a person's attention on issues they need to address.

"Nightmares probably evolved to help make us anxious about potential dangers," Barrett said. "Even post-traumatic nightmares, which just re-traumatize us, may have been useful in ancestral times when a wild animal that had attacked you, or a rival tribe that had invaded might well be likely to come back."

But this evolutionary alarm bell may not be so useful in today's world.

I believe that nightmares happen due to trauma that has happened to a person in some way, shape, or form.

I also believe that crushes are just fantasy relationships that someone wants to have for the experience of it. I am not really sure due to the fact that I have never had a crush or anything like that so I am not all that experienced with the topic.

the correct answer is the following.

one of the groups i belong to is the boy scouts. this is a problem-solving group because it has tasks that we need to solve in order to other people in different activities such as the rescue of lost pets, or elder people in need.

the other group i belong to is kids pro environment, and is an information-sharing group that tries to create conscience about the risks and problems that generate pollution in our cities. we share information to other students and parents on the importance of keep our communities clean and our skies clear.
