for the few past months i have had numerous occasions of me being half asleep and waking up and not being able to move and see a fairly big spider crawling towards me but i can get away from it even though i am awake and then i know that i get up or call for either my mum or dad, however on some occasions i have called my dad and remembers calling his name and by the time he was down stairs i was asleep even though i remember calling him i don't remember going back to sleep. last night it happened again and i got up and i remember doing it daily after seeing this spider however i can only clearly remember me seeing the spider then being half way up the stairs to my mum and dads room? can some one help or give advice or even know why this happens? thanks x
