Is seeing a mental image of a form believed to be Allah considered a true vision of Allah?

It is not permissible for a Muslim to imagine an image of Allah the Almighty, due to the saying of the Messenger of Allah, peace be upon him: "Reflect on the blessings of Allah, but do not reflect on Allah Himself." Imagination leads to depicting and anthropomorphizing the attributes of Allah, which is forbidden in Islamic law, as Allah the Almighty says: "There is nothing like unto Him," and "So do not coin comparisons for Allah." These imaginations are from the whispers of Satan, and their remedy is to seek refuge in Allah and cease such thoughts.
