Iin, that, i, feel,i'm, an, old, fat, man, and dream of being?

I sometimes feel like an old man lazy like him sleep for 18 hours and I can wake up eat and go back to sleep again.
I wake up on the bed and still lazy just stay doing nothing when I go out for a walk I always get tired of walking and sleep again.
in my sleep I don't dream freak dreams all the time but I imagine being that fat old bald man I see me like a real man not just a dream I clearly remember this view I imagine that man when I sit in silence alone and I sit alone most of time.
is it normal to imagine this man ,dream of him, acting like him and sometimes I feel like I can't get off the bed for being so heavy while I'm about just 60 kg and I do sport twice a week.
