The best explanation of REM sleep as “paradoxical” sleep is:

Because the brain is in a heightened state of excitement, while the body is virtually immobile.

In REM sleep, the brain exhibits activity patterns similar to those seen during wakefulness, leading to vivid dreams, while the body experiences muscle atonia (temporary paralysis), creating the paradoxical state.
