Solution 2:

Hypnagogia is a fancy term for half-awake or half-asleep. Personally, I prefer the latter two. The Wikipedia article says:

However, hypnagogia is also regularly employed in a more general sense that covers both falling asleep and waking up […] Threshold consciousness (commonly called "half-asleep" or "half-awake", or "mind awake body asleep") describes the same mental state of someone who is moving towards sleep or wakefulness, but has not yet completed the transition. Such transitions are usually brief, but can be extended by sleep disturbance or deliberate induction, for example during meditation

Solution 3:

This is called sleep inertia.

Sleep inertia is a physiological state characterised by a decline in motor dexterity and a subjective feeling of grogginess immediately following an abrupt awakening. - wikipedia

Solution 4:

There is the term "sleep drunk":

having trouble coming to full wakefulness after sleep, accompanied by intense confusion and disorientation, and even sometimes violent reactions and amnesia
