What's going on with my head?

i went to bed one night and barely slept for 10 minutes when i was struck with paralysis for like 2 minutes....eyes were open and only fingers could move, i felt tired but still was able to see around me and think in my mind.........if someone else was in the room i wouldve seen them but only i couldnt talk......i had some weird noise in my ear like radio frequency and white flashes.....my previous experience i had my arms crossed while sleeping for only 10 minutes and woke up only to not be able to push arms up with full force and then i sprung up in one motion with my heart racing....no way i couldve been dreaming because when u first sleep noone starts dreaming right away...it takes at least 45minutes to enter REM mode.......my encounters were only 5-10 minutes into sleeping.....i always check the time when i go to bed =)
