in the middle of the night

this has happened twice before and last night it happened once more. out of the blue came screams from ronnies room at just gone 10.30pm. he was trashing around screaming out for mummy, however ronnie was not awake. i struggled to hold him as he whipped frantically around in my arms. i tried desperately to comfort him but i wasn’t sure he could even hear me over his own screams. suddenly calm. i was taken back 3 years, snuggling him into me, rocking from side to side, tapping his back to the same beat as my heart, shhhing lightly into his ear. again the screams pierced the air and he was even more  frantic than before, and writhing with quite some force. he was coughing and heaving i was worried he might choke. i took him into the spare bedroom to lay him down, through fear of dropping him. before i could snuggle up next to him he was spinning round going complete 360, screaming out for me but then pushing away from me. constantly moving spinning, crawling, climbing the headboard, he flipped back and forth. then his hand found me again and he collapsed on a pillow, nestled his legs between mine and dropped straight back into a deep sleep snoring like a bear. the screams had stopped but all night he was frantic and constantly on the move. today he is no wiser, but we are all much more sleepy than usual. so what happened there? we will never know i suspect.
