Wow! Sounds like ghosts I've heard of or seen on Ghost Adventures.
I've seen 2 ghosts with color and shape now. I've seen lots of ripples in the air and some black/moving figures.
I went up north to see my relatives for the 1st time in 16 years and I saw a blue ghost boy by my bed lean over like an "L" saying he just wanted to make sure I was comfortable. I just woke up at night. I saw a twisting black figure go out the window. By the way, I like my relatives a lot and am sad I could not be there for so long. I was busy with school, college, my mental illness, and finally I went.
Recently, I was with my mom at Disney World, and I was mad but kept it to myself. I was on the People Mover and saw a somewhat complex monster/alien figure that looked like the shape of my anger, reddish and such warm-colored parts, sitting next to my mom in the dark. I only saw some of it materialize. I was told, it felt, like by God, you can be mean like this if you want or not.
