Last night , In my dream

Last night I saw her in my dream , When I saw her , I held her hand , When I held her hand I knew that it was just dream ,I talked to her despite knowing that this was just a dream , I tried to continue the dream by talking , I really had fear that if I woke up or if the dream stopped I would be alone .
What a crazy guy !
I know I don't have to be like that , And I don't know how to change this feeling.
