Am I mentally ill?

It has been a couple weeks for me ever since my sleep has turned to a weird part of my day. I feel like every night I go to sleep it might happen,and it happens when I least expect it.

Usually around 3-4AM on random days a voice wakes me up and calls my name. I am familiar with that voice but I can’t define whose voice it is. I sleep alone in my room at my parents house so it can’t be a person calling my name cuz every time I wake up there’s no one and the voice fades away,as if it just wants my attention for some reasons.

This might just be my brain tricking me into hearing voices because the last couple weeks has been kinda overflown with stress and projects but I am a creative person and I do not really go with the flow.
