Dr. Dave Hnida, the medical editor for CBS Denver, recently said he’s heard of a number of side effects related to the COVID-19 vaccine — including dreams of space.

Hnida told CBS Denver that people have vivid dreams when they’re recovering from the novel coronavirus vaccine. He said he’s seen reports of dreams about space, too.

  • In fact, Hnida said he has been told about dreams related to “Back to the Future,” which have included hover cars.
  • “Flying to the moon, planting the flag on the moon. Even somebody going out and taking Abraham Lincoln to get a Big Mac and having the staff want him to autograph the bills. We really think it has something to do with the immune response. They are temporary.”

Hnida told CBS Denver this is totally normal since the vaccine may interrupt your sleep cycle and REM cycle, which is when we dream.

There are some isolated stories about this. For example, in Pittsburgh, Pennsylvania, Richard Vetstein said he had bad flu-like symptoms after getting the Moderna COVID-19 vaccine, according to KDKA. He said he had vivid dreams as well.

  • “One of them was, I saved a Belgian town from the Nazis, so that was interesting. The other one, I was on the Titanic,” he says, “You wake up, and you’re like, ‘what was that?’”
  • Vetstein said he posted on social media about it and he received a number of comments from people who felt the same.
  • “A bunch of people commented they also had weird dreams, too, after the vaccine,” he said, according to KDKA.
