On the evening of July 15th, the man thought he saw UFOs outside his apartment in Hedemora.
To protect himself from the attackers from outer space, he picked up a pistol and fired several shots.
When the 23-year-old began shooting, the mother of his child, also in the apartment, called the police.
Even so, it took several hours of convincing as well as one last shot against the aliens before the man gave up his fight against the alleged attackers, local newspaper Dala-Demokraten reported.
No one was injured in the shooting, but due to the risk posed from the man having fired live rounds the man has now been charged with illegal weapon possession and threatening a police officer, wrote the newspaper.
Despite the charges, the police didn't feel threatened by the man, according to their own report.
"We do not believe that the threats voiced were anything other than the desperation of a confused person," wrote the police in a memorandum, also concluding that two shots were fired through the apartment window.
According to the 23-year-old, he fired several more shots, that hit and destroyed the UFOs that had come to kidnap him.
He said that the unidentified objects exploded when hit.
The man may have been suffering from a severe psychiatric disturbance at the time of the shooting, according to the psychiatrist who evaluated him.
The 23-year-old has previously been convicted of attempted manslaughter.
