being a nite-later

Am i insomniatic? Or...........

You know that i always taking a nap everyday when i have spare time haha, usually about 2-4 hours. I love sleeping ‘cause makes relaxing my mind. But I have some problems when taking a nap in the day, in the night hard to sleep under 12 a.m. For examples, yesterday I went to sleep at 2 a.m. and also the day before yesterday lol. Overall I’m enjoying being a nite-later. I cant like that when I’m on school season, school is cool -_-
