@ev2nana The causes of sleep interruption can be many.
Environmental/physical: is there a temperature change in the room? Do you have a bed partner who is restless, disturbing your sleep? Do you first cuddle under a lot of bedclothes for the comfort, then awaken when your body temp changes? Did you eat or drink within an hour of bedtime, possibly causing a sugar spike and drop in your system? Are you wearing pajamas or nightgown that are binding your movement as you sleep? Sleep apnea?
Emotional/mental: are there issues in your life that you are facing right now, that won't let you relax? Are you a caretaker for someone, and wake up to check on them? Is your brain unable to "turn off" to let you rest?
I hope you find a solution to your dilemma. Myself, I haven't had a decent night sleep in decades.
