ALSACAT is my comprehensive catalog of UFO sighting reports in Alsace, the region is the North-East of France, whether they are "explained" or "unexplained".

The ALSACAT catalog is made of case files with a case number, summary, quantitative information (date, location, number of witnesses...), classifications, all sources mentioning the case with their references, a discussion of the case in order to evaluate its causes, and a history of the changes made to the file. A general index and thematic sub-catalogs give access to these Alsatian case files.

Case of Salmbach, in December 2014:

Case number:



On a website called "UFO Consciousness", one "Olivier de Sedona" published on December 10, 2014 that a "strange shape" is "appeared", discovered on the wall of his room by a resident of Salmbach.

Mold had formed what resembled a little character with big all round eyes, "upright with arms at the solar plexus."

According to the "witness", this mold appeared totally randomly at first, and it reappeared after three days each time he had cleaned it.

The website asks whether this is a "simple Pareidolia", a kind of optical illusion of associating an inform and ambiguous visual stimulus to a clear and identifiable element.

The website published pictures, visible below in this case file.

A strange figure appears on a wall in Alsace


It's an odd discovery that was made by an inhabitant of Salmbach near Wissembourg in Alsace. On the wall of his bedroom mold shaped what may suggest a small figure with big all round eyes, straight as a stick with arms at the solar plexus. According to the witness at the beginning this mold seemed completely random and whenever he had erased it this form returned 3 days later...

The witness added the following detail: "What is strange is that it does not overflow along the body"


So, simple Pareidolia?

A Pareidolia is a kind of optical illusion of associating an informs and ambiguous visual stimulus to a clear and identifiable element.

For more information on Pareidolias:



Is it really necessary to comment? Traces of mold on a wall are not an alien, even the formed pattern may suggest an alien.
