I've got a little tale about 'phone weirdness'. Tbh it's nothing major and until recently I'd thought of it as funny rather than odd, but here we go...
About 5-10 years ago myself and my partner went to Jersey one summer for a relatively cheap, easy holiday. Upon arriving at our hotel we checked in and went to our room to find that it wasn't right and generally didn't seem to be in good condition, so for the first and only time before or since at a hotel, we decided to ask if we could swap rooms. I think my partner either took the number from the hotel room information book or did an automatic dial on the phone, (unfortunately I can't remember now) and rang the reception. They said no problem but that it may be a little while as they were sorting out arrivals. We didn't mind and patiently waited, watching the TV.
An hour and a half passed and we decided to ring again to check they hadn't forgotten about us. The receptionist was completely confused, saying that she'd sent someone up a while ago and they'd come back saying that the people in the room had told them that they didn't want to move rooms. We confirmed the room number again (it was the one they'd went to) and she said she'd send somebody up straight away. We waited for another 30-40 minutes... no sign of anyone... so my partner went down to the reception. He came back with someone fairly quickly and explained they were all really confused as they had no clue about any of these phones calls, but thankfully they were more than happy to move us straight away. The new room was spot on and the rest of the stay was fine, and we laughed at times times thinking, 'who on earth were we calling, some poor random sods (hotel staff and guests) were a bit harassed that day weren't they?' However, looking back it was a bit odd really.
I think there are probably 4 possible explanations:
1) The hotel staff couldn't be bothered, or didn't want to move us, and had hoped we'd go away. However I don't think this is the case because they were apologetic and seemed genuinely confused about what had happened. Plus they were more than happy to move us, and the new room was spot on.
2) We'd contacted a second reception at the hotel, however I don't think one existed. We never saw one and the reception staff never suggested we could have accidentely reached a different reception.
3) We accidentally contacted another hotel. I wish I could remember for definite where we got the number. There is a slim possibility we got it online but we definitely would have used the hotel room information book or the telephone itself (usually there's a speed dial for reception). We only would have looked online as a last resort. Nothing on either of these calls made my partner think that he'd rang the wrong hotel, and he knew what hotel we were at.
4) The fortean explanation: We rang the hotel... in a parallel dimension!
I think the most likely explanation is number 3, although it seems unlikely to some extent. Either way it's likely that there's someone out there, somewhere, with an odd/irate tale about how a hotel they were staying at were determined to move them to another room due to some mysterious, but persistent phone calls.
