Are your dreams different when you're sick?

When I have the flu, and my temperature is maybe above 100, my dreams have a strange sensation. I can't quite capture it, ever. All the other times I've been sick, my dreams are either this huge mass, filling my everything, and I MUST, HAVE TO take it out in needle sized sections. I feel overwhelmed, but also calm and annoyed. I don't see anything in my mind's eye, everything is felt, yet the color of the dream is maroon or pewter with a grid. I found the dream enjoyable.

That, or I feel like a lion lying on a surface of soft play-doh spikes, spiny like seahorses. They taste like dried durian, the spikes. The spikes, they roll like waves and hurt my back. It was yellow.

But this recent time, I actually hallucinated when awake, the rope/stream of frozen running poisonous chemical milk, was rough and smooth at the same time. I think I was talking aloud a stream of mathematical nonsense. I also think I sleepwalked. The eye contact of others suffocated me, the eye contact wrapped around me tighter in pulses, I think I started hyperventilating when it got really tight, so I ran to the sofa and tried to sleep there, but the people were chasing me. This time around, shit was a lot more vivid, I actually went online in my dream, reading scary blogs on tumblr or something. I ate a pear, I think.

I can say that the dreams were a lot more sensory more lyrical and less narrative. Not much to see, but a lot of feeling. And also very hard to describe.
Do everyone's dreams change when they have the flu? In what way, is it similar to mine?
