As more people get vaccinated, doctors are learning about new and unusual side effects.

Rashes at the injection site, developing a metallic taste in your mouth and fatigue are all symptoms of the COVID-19 vaccine that can be explained and that are common.

But why are some vaccinated people dreaming about outer space??

Doctors say some vaccinated people are experiencing weird side effects including dreams about space. People have reported flying to the Moon, planting a flag on the Moon, “Back To The Future” dreams filled with hovercrafts and hover cars. And though this one isn’t space-related, the dream about going out to McDonald’s with Abraham Lincoln for a Big Mac has to be mentioned!

According to medical professionals, it’s believed the response to the vaccine may interrupt sleep cycles, especially the REM cycle where we dream.

The say that if you have anything weird going on after receiving the vaccine, the most important thing to know is you’re not alone and they are generally not of great concern.

But if you do something unusual and you are worried about it, talk to your doctor for more information.
