Yes, a meme is where I get all my facts

Yes.
This isn't an ordinary meme in the sense that it takes an image (e.g. a bus and a train crashing) and puts it in a different context / adds text that uses the image as a metaphor (e.g. the bus and train standing for other things).
This is a (photoshopped) picture in which the sense of the image is taken literally by the caption. So yeah… when it takes itself seriously, I can also take this scenario seriously and just think about it.

Edit: But I mean jokes usually also take themselves seriously and you don't think about the scenario. I think the difference is that I don't see anything unordinary or funny in this picture; I don't see a joke. I think playing the Doom soundtrack to an unborn child is something completely reasonable I can imagine doing; so I just focus on what real implications this scenario had (not telling the future mother, which is still bad imo).
