The same person appears in all of of my dreams and lately she seems very familiar. Do you know if she is exists in real life or is just part of my dreams?

I understand if this person is in all of your drama n she looks like a familiar face to you it means she was once alive or it is someone from your past you now but have forgotten about but just remember dreams can also be very vivid and give the allusion that what you see is really happening and you now that person
