眠い (ねむい (nemui)) represents "sleepy" (Level: N4) and typically represents I-adjective. Describes the feeling of wanting to sleep. It is not a verb for 'to sleep'..
On the other hand, 開く (あく (aku)) translates to "to open (intransitive)" (Level: N4) and is used for Intransitive verb. Used when something opens on its own or is opened by an unspecified agent. Mixing these up can sound unnatural to native Japanese speakers!
