Sudden strange pattern on interior wall

My husband I I bought this house built around the late 1980s. Today we noticed this very strange pattern on the wall in our room. He has been in the attic and checked for anything with burnt wires, water or the such. The switch inside is dry and no burnt wires.
Has anyone seen this type if thing before?
Please help
Thanks

Welcome to the forums.

That looks like water damage.

Kind of looks like an electrician cut out a path for his wire then there was a really bad drywall repair that followed.

Looks like water damage to me also although there are no water stains.
Are the wrinkles soft or hard?

I would tape a piece of plastic over the damaged area and leave it for a fer days. If moisture shows up on the backside of the plastic then it is water damage, If none shows up then odds it is a poor drywall repair.

So you have lived here more than thirty years and this is a new development? If it is new it must be water damage . Water is running down the wall and loosening the paint from the drywall or plaster. I bet if you had timed this right you could have poked a hole in one of those blisters and seen water run out. Is this an outside wall? Also it looks to me like the switch plate screws are rusty.
.

If Xsleeper is correct this must have been done with a 1” putty knife. But I am holding out for water.

You want to fix this so I would forego the plastic and just peel off the loose paint. Then see what you have. Check that switch box again for signs that water has gotten in. It seems odd that water runs down right into a switch box. Anyway do some minor exploratory surgery and find the problem then solve the leak. Then fix the wall. We can tell you how to do it.
If Xsleeper is right then breathe a sigh of relief and scrape it off and we can tell you how to fix it.

IF you look on the patching and plastering forum for a thread titled something like this: “Just found this on bathroom wall: is it efflorescence?” You will get another example of water loosening paint from behind. Sorry I don’t know how to link to the thread.

Tightcoat, if you know where the thread is, just open the thread & highlight the information in the address bar. It will be https://www.doityourself.com/forum/ etc, etc.....
Then copy it (shortcut to copy is the ctrl key & the "C' key at the same time).
Then just put your cursor in the text box in this thread & paste it. (Again: ctrl & the "V").

(the ctrl key & C will copy....... ctrl & "V" will paste)
