What could these vivid dreams mean?

Lately I’ve been falling into the deepest sleep, like I feel like I’m awake in them, but I cannot do certain things. In one dream I woke up, stood up from the couch (I fell asleep on the couch on thanksgiving day) but I couldn’t open my eyes.. like they were stuck? It was the strangest thing. And then I find myself gasping for air when I wake up. Then two days after that, I had another dream where I was awake again. But this time I couldn’t feel my arms. And it felt like pressure in my chest, like I stopped breathing. But immediately, gasped for air and woke up. It actually really scared me and I was afraid to sleep again. I’m having these dreams more and more, I wake up gasping for air And pressure in my chest. One dream I saw a little boy, I have no clue who he was. But he said he was my brother. He was so cute. And I tell my mom about it and she told me she had a miscarriage and it was a boy. Another dream I had, there were people standing all around me. I asked “is there someone here that is evil following me” because I was stupid and followed one of those online reading things where you give a birthday, and the last one said there’s evil around you, i unsubscribed. One person in the dream said “yes, there is something evil following you” this was a week after I read that reading. And then I saw some videos about shadow people very randomly... am I going crazy???? Lol
