Cats can dream while they sleep! If your cat's limbs are twitching while dreaming, it's almost certainly dreaming. They might be dreaming about running, playing, or something similar. Just wait for them to wake up naturally.
Of course, this is also supported by scientific experiments. French scientist Michel Juvitt previously discovered in experiments that cats exhibit some muscle activity when they enter a sleep stage, such as tremors in their ears, whiskers, paws, and even forelimbs. This has been interpreted as a manifestation of cats dreaming.
