i had this dream about a year or less ago but still think of it as it was a frighting experience i was under bit of stress at the time so that could be relevant. i dreamed i was in bed and first it was very quite too quiet then i could hear a loud weird noise i cannot describe i felt like my body was rising upwards out of the bed i was trying to shout i heard a family member going into the bathroom and i was shouting them but they couldnt hear me i felt like something was covering my mouth and stuffing things in my mouth to slience me i cant remeber the rest but it was rather frightening .
