I think saw 'Something' that I shouldn't see ...

Right, so I woke up 'bout 6 something to have a sip of water..then I went to the toilet..Okay,then I was walking back to m room when I heard something..so I was thinking,okay,if it's a ghost,I'll shout out real loud,and my mommy and poppy will rescue me...so I prepared..(kinda stupid,right?)then a black figure jumped out of the room..I didn't even get to shout out...I was like..I mean,I sort of gasp...then cried out. Who do think it was? My mom..but,I saw a white figure that float past me...and I stood real still...like,froze on the spot...I told my sis..she laughed and then turned solemn. She ask if I was making it up,I swore I wasn't. I told my mom too,but she told me not to make up stories...Geez..nobody seems to believe me...Guess I really was seeing things..but..I'm sure I wouldn't make a mistake..I know it's in the morning,but that doesn't mean I'm still blur..right? This subject has freaked me out for days..And my sis told me to never shout when you see these 'things',just walk away and pretend you didn't even see it.So guys,really hope you don't see these 'things'...cuz it's really freakin' scary.and it might give you a heart-attack..haha..-.-...
