In dreams, floating signifies a lack of control. It often represents life situations where the person feels like they are not rooted to the ground. Floating can signify feelings of helplessness, weightlessness, and petrification.
Someone might see themselves floating in their dream if they are feeling that there is no foundation for them to stand on in real life or if they feel like they don’t have any control over their future. It may also be a symbol for feeling that life has become like a fantasy or dreamscape to them and is not something that will last forever.
People who float in their dreams can feel overwhelmed with little escape routes or they may feel as if they are drifting through life without an anchor to hold on to. The act of floating also means that the person is feeling rudderless, either because of an external force, such as drugs or alcohol, or because they are lost without any sense of direction and getting into unknown territory without being sure about how things will turn out for them.
