I don't know it's problem or normal

Can you clarify your question please

The best sleep time is at night, as daytime sleep is stressful for your body. Indeed, the number of hours of your sleep is very few, so it is necessary for your body to take enough rest, but the hours of sleep at night help you wake up and be comfortable, and every hour you sleep at night helps you more rest and to be active. However, you may also sleep two hours during the day, but because you always feel that you will not be able to sleep, then these thoughts are what bother you and make you unable to sleep, so try to relax and do a simple sport activity to make your body relax, such as running or swimming or even you can read until you feel sleepy, then you rest for two hours at most until your body gets used to these hours of sleep and needs them continuously.
