Sense of foreboding

Sense Of Foreboding One of my online friends lived as my neighbour in a town I never saw before and I had no family and friends.
We only held contact via landline calls.
Then one day he invited me to come to his home and I found his door unclosed and stepped in.
As soon as I stepped in I was trapped and I realised that he was a non-human, kind of a computer, I can't explain it better.
I couldn't see him, only sensed in the air that there was something very wrong and I was in danger.
On the floor in a small room I found 8 flat apparatuses that worked, they looked similar to seismographs.
I was glad when I suddenly awoke from that dream, it was 6:30 am.

The next morning I asked how he was doing and he told me that he called the ambulance at night because he was so breathless, exhausted, couldn't breath and he told me that he was connected to several machines to monitor heart, blood pressure.
His neighbour came to collect him at 6:30 am…
