Living with Sleep Disorders

Hi, all.
I want to share my strange experience a few days ago.
I am a medical student. I usually sleep 12.30 or 1 at night and wake up 6.30 in my hostel. But on holidays i wake up till 10 in morning.

I couldn’t sleep well that night ,but during morning 6 to 8 a.m i had very deep sleep. I was feeling much weak, tired in sleep but was conscious about my condition in sleep(that wasn’t dream). I was feeling so weak that in sleep i felt that i couldn’t move any body part voluntarily.i felt my increased heart beat ,i felt that something is rushing towards my brain, i later felt pressure in brain/head ,and heard strange sounds in ear with urge that something want to burst from my ears.

I wanted to woke up but i couldn’t voluntarily move my body or open eyes.(exactly like in when we fall from height in a dream or get feared and feel that we can’t open eyes or move)
I don’t know how i woke up thereafter or don’t remember but i felt much weak and noted that my ears were somewhat wet (like after listening to very loud music in headphones).

When i told this to mother,she said that she had similar symptoms and were because of a small blood clot that was obstructing artery in brain.

She took medication and became well.
This had happened to me 3-4 times.
I rarely play and my lifestyle is not so healthy,
am not performing well in my exams and take much tension.
What should i do? If anyone with similar symptoms had undergone treatment plse advice .
Can such things be heridatory?
If anyone knows the answers plse reply to my email address.
