My body feels like its moving when laying down but i'm not actually moving? can it be anxiety/ stress? circulation?

Yes to all but...: Dizziness is common and broad symptom. There is a fairly common problem called benign paroxysmal positional vertigo, bppv. Brief spinning occurs when laying down or turning over when laying or looking up in a specific way. This problem is often cured by "repositioning" particles that have become free floating in the inner ear. See ENT doctor for this.
