The phrase "see in mind" means to imagine or visualize something in your head. There are many antonyms that go against this idea, such as forget, unsee, ignore, disregard, or overlook. When you forget something, you no longer have it in your mind, and when you unsee something, you reverse the act of visualizing it. Ignoring, disregarding, or overlooking something means that you are not giving it any attention, which also contradicts the idea of seeing in mind. Antonyms for "see in mind" acknowledge that not everything we imagine is desirable or worth keeping in our thoughts.
