Consider this scenario, You come home from work, all tired, and put some water to boil on the stove and sit on your sofa with your eyes closed. And you are on the verge of initiating/falling asleep, suddenly you remember the gas was on and your brain sends those impulses and gets aroused from the half-sleep state for you to go switch it off. This hypothetical scenario kind of sudden unexplained arousal happens to me while on the boundary of sleeping/being awake without any explanation or underlying cause, exactly while trying to initiate sleep. Hence I have to rely on meds. Can anyone help me with this, I have had this issue since 2015.
