Reduced baby movements?

Desiree • CA • NC. RH neg. married. Momma to a almost three year old.
Im 22.5 weeks, and I've noticed that my baby girl hasn't been very active today. I've actually barely felt her at all. Is this normal? Or should I wait to panic until she's been nonactive for a few days. I also had a nightmare about reduced movements and her passing away last night so I feel like I might be paranoid because of it. She's usually always moves when I lay down though, and I haven't felt an movements yet tonight.
