scared to sleep!

i was in full sleep mode at 1 a.m. when i heard my mom screaming in the night "get away from my door". after i heard my mother scream this a few times i decided that it might be in my best intrest to figure out what was going on. so i rose from my bed and opened my bedroom door to see my mom in a frantic holding her phone still screaming "get away from my door!" then i looked to my front door to see a black figure banging on my front door and turning the knob that was locked realizing he couldnt get in then trying to push and beat his way in. by htis time my mom had already threatened to call the cops several times and had told me to go lock my window. i was too scared to even move so i didnt lock my window and proceeded to listen to screaming and banging. finally my mom sed again im going to call the cops and then i heard the figure say "its meeee!" knowing the voice me and mom moved to the door and opened it to find my 20 year old brother dressed head to toe in a big monster costume saying he was trying to get in.
