Hi, Few Months Ago, I Have Been To A Hospital

Hi, few months ago, i have been to a hospital where the doctor diagnose me for TIA/mini stroke. i am a healthy male 29 with no history of any disease known. not a smoker and i dont consume alcohol. that day, i suddenly feel numbness on my left side and paralyze half of my body like a stroke patient. it occur for 5-10 minutes for 3 times consecutively in 1 day. later i was admit to a ward.
(it occur once for 5-10min--> then-ok can walk after--> 15-20min reoccurred then ok and reoccured and then ok..)3episodes. now the doctor still doing some test, still i feel perfectly fine no occurrence for the past 5 months.. now i'm on med uniaspirin and simvastatin 40- skip regularly due to work.

not known to the doctor, about 1 hour before the case, i was sleeping and having a light headache.. was in deep sleep when suddenly i heard a loud knock on the door. i wake up instantly and went for the door then take my bath. i still felt the headache, the first episode occur while i was sitting after prayer (muslim prayer) around 30-45minutes after sudden the wakeup.
so is it possible that the case occurance due to above reason? sudden wakeup from sleep while having headaches. i also dont have much good sleep for the past few days before the case.
