Is the movement of the tongue during sleep, reciting the Qur'an and prophetic odes, considered dreams, or does it have other connotations?

The sleeper is not held accountable until he awakens, as the Prophet, peace and blessings be upon him, said: "The pen has been lifted from three: from the sleeper until he awakens, from the child until he grows up, and from the insane person until he regains his sanity." We do not have knowledge of dream interpretation, but what you see may be an indication of goodness and blessings.
