[Star Trek TNG] Do other galaxy class Federation starships experience insane scientific mysteries too? Or is it only the flagship Enterprise?

and what about Klingon ships.  are they having crew members disappear because of phase shifting and falling into temporal time loops?

Over the Enterprise-Ds exploration career, quite a bit of the weirdness they experienced had already happened, and they were called to go check it out.

As another commenter mentioned, a lot of it also was that the Enterprise went towards the weirdness and so got a bigger portion than most ships.

There's one other factor that nobody takes into account- most of the exploration Galaxy class ships never made it to retirement. They almost all ended up destroyed or lost, including the Enterprise-D. Other ships undoubtedly encountered things like the Enterprise did, and never made it back to report about it.

Lastly, there were also more than a few events that occurred or were survived because of that particular crew on that particular ship. When you have the only Klingon officer in Starfleet, you might have Klingon issues. Same with having the only sentient android. When extradimensional entities have a thing particularly for the Captain or even a specific engineering ensign, weirdness is bound to ensue. There are probably hundreds of new conditions in the Starfleet Medical Manual with only 2 doctors ever having treated them - Pulaski or Crusher. New states of matter only ever seen by LaForge, etc. 

Most ships would have not even had the ability to detect, identify or interact with some of the anomalies that the Enterprise-D did, because of its crew.
