Night light??

Okay so I’m 20.... my husbands gone a lot but growing up I always had a night light in the hall bathroom. Just enough to give a little light into our rooms. I feel ridiculous because to this day I still have one in my bathroom unless my husbands in bed with me. I’m not so much scared of the dark. I’m just afraid when I’m alone? Is this bad? I feel really dumb and childish if it’s not on at night.
