No it wouldn't. When properly focused, light originating from a particular point takes different paths into the lens, then all those paths converge to a single point on the focal plane.
In addition, light from any other direction is sent to a different point on the focal plane. This allows a 1:1 mapping from points in the field of view to points on the focal plane.
When the focus is off, the different paths that light takes from a point on the source to the eye do not converge and strike different points on the focal plane. In addition, these points may also be struck by light coming from other sources.
This divergence means a point source would activate a region on the plane, not a point. Eliminating other sources would reduce one source of trouble, but it is not sufficient for detailed imaging.
Your example of a fire is not a point source. It would have brightness differences over small distances. These differences would be smeared out as the focus is lost.
You can test this yourself. In an otherwise dark room or hall, you can image a bright window or television on the opposite wall with a magnifying glass at the correct distance. To simulate a myopic eye, just move the lens a little bit away from the wall.
