<human>: Can you summarize the given text in a few sentences?

Hey Reddit.

A couple of weeks ago, I accidentally overcharged a battery in the night, and to make a long story short, I wound up snapping awake to discover my carpet on fire. Not a big fire, but as you can imagine it freaked me out pretty bad, and it left a few nasty burn marks on the ground. Since then, I've been a little overzealous in unplugging electronics before bed, but I digress.

These past 2 nights, now, I've been snapping awake in a panic thinking I smell my carpet burning again, with last night even having a half-waking visual hallucination of flames. I know it wasn't real because there was no evidence of further flame when I checked it out, so I figure it was a partial nightmare, but nonetheless I've had this happen two nights in a row after a week of no problems.

Is this just a sort of PTSD reaction? Tonight's paranoia and event makes no sense, as the only 2 things plugged in the wall at all are my phone and lamp, so I *know* there's nothing to cause an issue. Is it just paranoia causing my senses to go into panic mode and smell the remnants of burned carpet? This is just getting infuriating and terrifying the more it happens. Is there anything that can be done to help me move past it?

Thanks, and I'm sorry about the wall-of-text. I literally just snapped awake, and upon discovering there was no danger, decided to write this post... so I'm a little sleep-addled still.
<bot>: a couple weeks ago I awoke to my room on fire. Now I'm paranoid and keep thinking I smell it again, making it hard to sleep. What do?
