getting sicker

Friday, was given antibiotics by Dr. late in afternoon.
Fri., Sat. and Sun. was running high fevers, fell asleep on a dime, had dreams that seemed so real, I still can't figure what's up or down.  I had dreams about boyfriend, and actually did try to go out with him with 102 fever - it didn't go well, but trying to make sense of everything else, it all became muddled, and I don't know what I said, what he said, and don't remember talking to him Sat. night.
Never picked up the pills until Mon. afternoon when I had to pick son up from school.  I just didn't trust my driving with the high fever.
Told my boyfriend today (looking at call logs) that I have no clue what we talked about Sat. night.  And, that makes me afraid.
Then, I was sleeping, the phone rang, my son answered, and thought he tried to wake me that my ex had to call 911 because my daughter wasn't breathing.  When I woke up, the phone had never rang.
Has anyone been that sick that they start dreaming things that seem so real, but didn't happen, and you're afraid to ask?
