Could there be something spiritual in my friend’s house or just coincidence?

Assalamu alaikum, I need some thoughts on something weird that happened. A few weeks ago a friend of mine who isn’t Muslim but is curious about Islam told me he’d been getting repeated bad dreams. I won’t go into the graphic details, but he said they kept happening and always took place inside his home. The same dream would show up in different forms and it scared him so much he became afraid to sleep. I told him to listen to Ayatul Kursi and recite it before sleep; since he can’t read Arabic he was reciting it in English. He says he hasn’t had a bad dream since and now makes a habit of saying Ayatul Kursi every night out of fear - which I guess is fine, haha. Last night I decided to sleep over at his place. Wallah I couldn’t stay asleep for more than 10 minutes at a time - kept waking up feeling really uneasy, so I gave up around 4–5am and played games until I left around 7am. Later when I got home, exhausted, I took a nap and had the exact same dream my friend had described: the same events and the same location. I thought that was strange, then remembered he’d told me about it weeks earlier - and the one night I stay over I get the same bad dream that supposedly happens in his home. I know scholars mention three kinds of dreams: good ones from Allah, dreams from our own thinking, and ones from Shaytan meant to disturb us. So I’m left wondering: is this just a coincidence or might there be something spiritual going on in his house? I don’t want to make this long - if anything’s unclear ask and I’ll explain. JazākAllāhu khayran.
