Buckle up folks, this might get scary

Hallucinate much?
So sick and nauseous started at 2 am this morning...so sick but couldn't throw up this continued until around 6 or 7 am when I hallucinated and it apparently made the nausea stop.
I was awake already begging to puke. I couldn't so I got back in bed and all of a sudden I was in a darker than normal library looking place there was a calm I have NEVER felt before as close a I can get to describing it is serene I felt someone take my hand it was a he but I couldn't see his face dressed darkly and he was pretty tall he seemed to be right in front of me but also far away. I noticed the oddest details, tall fairly thin, blond, I don't know anyone like that and it was just weird b/c the whole thing lasted maybe 15=30 seconds.

I walked in the library called for mike and then someone took my hand and said, It's starting." I asked, "what is starting?" He said, "Your death." I pulled my hand away and said ,"No." then I realized my eyes were open and I was looking at Mike he wasn't holding my hand and I felt calmer than ever have before and my nausea was 100% gone.

I tried to find it again but couldn't. I have to assume it was a hallucination.
How whacked is that? It wasn't scary AT ALL it was the total opposite of scary it was very calming which it what makes it weird.
