Bad Dream or Reality?

I had a really unpleasant situation last night. I'm not really sure if I was dreaming or if I was really having problems.

I felt like I was lying there, half awake and half asleep. It was like I was aware of things going on, but I couldn't do anything. I couldn't move my hands or my feet or say anything. I thought I was lying in my bed in the bedroom and that I was awake.

But I kept not breathing. I could hear DH breathing. He would take four or five breaths and I just wouldn't be able to breathe. Then suddenly I start breathing again, and take a couple short shallow asthma-like breaths. Then I would start to relax and stop breathing again.

Then DH got up to go to the bathroom, and I managed to move enough to crawl over to him but not talk to him. Then it started again.

I was up when DH left for work this morning. He says I must have been dreaming. He was aware of me being upset about something I was grunting some or something. But he didn't notice me having any breathing problems.

So was it really just a dream?

I've been up for several hours now, but I am so tired. I really didn't sleep well.
