My boyfriend kisses me in his sleep every night

During the night I tend to move a lot trying to get comfy my boyfriend is a very deep sleeper so he never notices. Everytime I lay on his chest he gently kisses the top of my head and wraps his arms around me. Ive mentioned it to him but he never has any recollection of doing this but it always makes me feel so loved. Im so lucky to have him in my life
