I see dead people

Lately, I've been dreaming about dead people.  Actually, my dead friends have been visiting me in my dreams.

I'll have some arbitrary dream about crazy shit, and then, behold, my dead friend knocks on the door.  I open the door, and standing there is my friend.  We sit and chat like old times.

My dead friends look exactly the way they did the last time I saw them, even if it was 15 years ago.

We chat, enjoy each other's company, and then the damn alarm goes off.  I wake up startled, confused, and slightly upset over just what happened.

I'm not sure what all this means.  Maybe I've been eating too much salsa before bed time.
