It is possible to feel nostalgia for things that you have not personally experienced. This is known as vicarious nostalgia, and it occurs when you feel nostalgic for a time or place that you have not personally experienced, but that you feel connected to through stories, images, or other forms of media. For example, you may feel nostalgic for a specific time period, such as the 1950s, based on the stories and images that you have seen, even if you were not alive during that time.

Additionally, you can also feel a form of nostalgia for something that you have not experienced but you have a strong desire to experience it, such as a place, culture or a way of life. This is known as imagined nostalgia, it is a form of longing for something that is not real or has not yet been experienced but it is imagined in the mind.
