Welcome to my dreams!

1. [Non-Lucid]
I'm in some sort of cube thing in Minecraft, I keep falling from cube to cube, it hurts and takes half a heart every time, there are spiders and creepers around the place, I think I make it to the bottom, I say something but I forgot.
Someone (Lewis?) is chasing me as I'm trying to run away, he grabs me and I fall to the floor, I'm now laying on my back and hes now on top of me with a sharp razor-blade in hes right hand (his right), hes about to end me then...my alarm went off and I jolted awake.

2. [Non-Lucid]
I'm at the top of some stairs (1 step then turn right then stairs) I take a while to get down the step, I'm grabbing on the handrail to the left for dear life as im scared of falling down the stairs, I put my left foot forward ((I can actually see my leg)I think I'm wearing white socks), I'm really scared at this point it takes me at least 10 minutes to get down this step, I think I sit down and shuffle down the stairs.
