Do you believe in dreamcatchers?

My now 21 month old was waking up screaming in the middle of the night about 3 weeks ago, he was also screaming before going to bed and crying a lot with us like we literally do not know why. Out of nowhere. He’s slept through the night since 4 months old of course had phases that woke up wanting mom in the middle of the night but never something like this. I prayed a lot too in there with my baby crying struggling to fall asleep at 9 pm. (That is really late for him usually). We also bought a dreamcatcher for the hecks of it and it seems to have helped. It was 10 really rough nights for us. What do you think of dreamcatchers? Do they really work? The first night we used it he slept great, and we show him his room to play in before bed so he can be comfortable in his own space. But he did ask me to show him the dreamcatcher(he is a smart baby that is curious and sees every little detail, even in his room) so I showed him and explained its to “take away bad dreams and make him feel better” so he touched it and went on with his day. Its been about 15 days of better nights…
