I don't know what the hell just happened or if it's related?

This was so frightening, it's evening now and I'm still rattled. I had my first ketamine IM treatment last Friday, and have my second tomorrow. I have no idea if it's related as it seems kind of long after the treatment for this to happen. I don't practice lucid dreaming or anything like that either.

I set alarms for 11:30 am and 12:30 pm since I woke up very early the day before. I woke up around 10 am naturally, and turned off the 11:30 alarm. I then was very sleepy/drowsy and laid in different positions for an unknown amount of time before falling back asleep.

at some point, I thought I woke up. I saw my room, and was definitely conscious/awake on some level. I remember sitting up, getting out of bed, but immediately feeling like I was in a dream. I looked at the time, which was 4 pm, and was completely shocked and confused. I remember clearly doing the math to see how long I'd slept if it was 4pm and being shocked again. Then I looked at the clock on my stove which was saying 6pm, and I was even more stunned. 

At some point things got more confusing. I woke back up, I felt for a moment like I really was awake this time and the previous experience had just been a dream. But as soon as I "stood up" and got out of bed (same sequence as last one), the time was different, around 1 pm. I went into the kitchen/living room (same sequence) and saw that it was dark outside my window. I began feeling strange, almost manic. I looked out the peephole of my apartment door and saw that gifts were placed at every doorstep, but that someone was running around hiding, wielding some kind of knife. I ran back inside and pushed the door closed as the person knocked.

Then it happened again. I woke back up, felt like I really was awake this time and the previous experience was a just dream. Stood up again (same sequence), went to the kitchen and my apartment door. I opened my door and there was a blue wall in front of it. This terrified me and I had a conscious thought of "I am hallucinating. This is psychosis right now." I went to my phone and called my psychiatrist. When he answered, I actually feel like I spoke the words aloud, but they were garbled. I remember him saying that I should call 911 and go to the hospital, that I might be having a manic episode of some kind. I went into the living room and tried to call or text my mother, which I had trouble doing. 

I think I thought I actually woke up about 4-5 times. There were other dream elements throughout, but the actually thinking I was awake and waking up was terrifying. I really thought I would be going to the ER, that I had to call 911. I felt like I was actually trying to do that. When I woke up it was almost 2pm, so somehow I had actually shut off my 12:30 alarm. I missed class because of this. What?????
