"Wake up look me in the eyes again" could be interpretted as "[I] wake up [and I want you to] look me in the eyes again," meaning he was dreaming of someone and wanted them to appear alongside his bed when he wakes up. "I need to feel your hand upon my face" further solidifies this, as the person isn't physically with them, but he felt this in his dream and wants it to continue when he wakes.
"Words can be like knives/They can cut you open/And the silence surrounds you/And holds you" can be shown as a type of rejection in a way. He tried to make something work with someone he wanted to be closer to, but it did not exactly work out. And that rejection "cuts you open." But since they were close before, that "silence" that "surrounds you and holds you" haunts him because of how close they were, but that tension of one not wanting the other made them stop being so close.
This is further shown through the lines "I think I might've inhaled you/I could feel you behind my eyes/You gotten into my bloodstream/I could feel you floating in me." I first thought this was about a breakup, but these lines made me think it was a moment of realization that he fell in love with someone. He THINKS he might've inhaled the person. He won't stop thinking about them, they're the thought that plagues his mind and bloodstream.
The lines "The spaces in between/Two minds and all the places they have been" shows their closeness and how alike they were. So when he says, "I tried to put my finger on it," he is possibly trying to figure out why the other person doesn't feel the same if he himself feels they are compatible. "I tried to put my finger on it" can also mean he is trying to put his finger on why exactly this person is constantly crossing his mind."
TL;DR
He had a moment of realization that he was falling for someone who does not feel the same about him
