Segmented Reality

There were multiple segments, last night, from waking multiple times.
And henceforth are fading more and more.

First, there were three of us, surrounding a taller man, but sitting in a school desk. The kind where the chair is attached to the desk, and the top of the desk flips up.
He wasn't a lanky, but on the skinnier side of the spectrum. He had a shaved head, though I feel like if his hair were grown out it would be dark.
If I remember correctly, we were taunting him, or questioning him. I do know for a fact, he was not making things easy for us.
The last image I recall, is a butter knife stuck in the top of his head. But the consistency was similar to rubber, or perhaps the ballistic gel so often seen in crime scene TV shows. One of the other two had thrown it, and it had stuck.
None of us had expected it to stay, and the man did not flinch, nor was he hurt.
Something had provoked that action, but I cannot recall what it was. And only the one threw it, though we were all armed with silverware for some reason.

Next, I was in a room with Alex, but having flashbacks. I wanted to talk to him about them, but was nervous.
The flashbacks were either based on a dream, or a much earlier experience I had - I cannot remember at this point.
(In real life my dream stole the topic from a book I am currently reading.)
I just knew that these thoughts plagued me, and I wanted to tell him, but was unsure how he would respond.
My dream, withing a dream (or memory, perhaps) was that I had "gone down on" and sprightly red-headed girl, who had never experienced that before.
My dream was inconsistent, in that I was still dating Alex and he might be offended, and that I wasn't dating Alex, so he couldn't be bothered. And then, of course, the thought that even if I was dating Alex, why would that bother him?
I woke before I did tell him, but after falling back asleep, dreaming, waking up, and falling back asleep again I resumed this dream, in which I did tell him.
But I woke up before a response was given.

Finally, another dream with Alex.
We were in a darker, basement room, not as large as a gymnasium, but spacious like perhaps a banquet hall, one that is similar to what is rented out to wedding parties?
There was a TV on a rolling cart, reminiscent of high school.
I remember it being sunny outside, because you could see the sun creeping between the curtains.
There might have been others, but I know for a fact Alex and I were there to prep for space travel.
We had been selected for the next space shuttle mission. I don't remember what our tasks would be, or why we were chosen. Just that it was intended to last two years.
Again, I was scared. Leaving everything behind for two years. What would change.
And I was scared of losing Alex. Even though we were going together. I think my worry came from a short instant where he left the room and did not come back as quickly as I expected.
I was slightly worried he would change his mind at the last minute, but more than that, I was worried that if they couldn't find him before it was time to go, they would just send me on my own.
I was scared to death of being alone, on my own, for two years.
And there might have been others with me besides him, but...
It is entirely possible to be alone while surrounded by others.
And he was the one I knew, he was my security blanket in this particular case.
I could talk to him. He knew me. I just wanted one familiar face.
