Conversation With An Elder God

A man is near dying and wants only to find a final resting place in a desert area.
Suddenly he finds himself surrounded by strange looking little people. He then passes out.
The man then dwells in a world of swirling colors for a time. The little people care for him, as he sleeps in perhaps a coffin.
At last the little people remove him from the sort of coffin thing that has been his home. His pain is gone and, aside from a little dizziness, he feels good.
The little people then want the man to do repairs to the place where they and he live.
The leader of the little people leads the man to a sort of flat panel that holds a picture. The picture is of the room in which the man finds that they stand. The little fellow activates a switch of some sort and the picture moves and talks. The talk is in a foreign language, a language different from the one used by the little people, at least judging by the sound of it.
The picture in the panel illustrates repairs of the room. The room is part of a larger, saucer shaped structure. The saucer shaped structure is obviously a flying vehicle.
Once shown repair materials and tools, the man begins to repair the damage to the ship following the training film in the flat panel as best he can.
The repair work is physically hard, too hard for the little people. It initially requires much of the mans strength. As the days wear into months, he becomes stronger; much stronger. The little people can't really help with the work. They're not only too small to be of any real use, they're also too dumb.
His saviors are some sort of mentally retarded midgets. Nice guys, mind you. Guys who saved his life. But really dim bulbs.
As time passes, the man discovers that the little people can't eat much of the food in the saucer ship. This tells him that the saucer ship doesn't belong to the little people, leaving the question of ownership a mystery.
As the months wear on, the man begins to see that the little people are in some sort of trouble. They're, of course, ship wrecked somewhere other than their home. How they even got as far as they have is a mystery. They're almost all not only dumb but also very clumsy. There's only one, very young, child among the little people and it's appallingly dumb. The rest of the little people seem to dote on the one child, not so much out of pity but perhaps out of pride. The man doesn’t know exactly what to make of the situation.
The man himself doesn't need much. He spends his nights in a little coffin-based world of swirling colors. The coffin thing is obviously a medical device of some sort.
One night, at least most of the mystery of the little people is solved for the man.
A large being opens his coffin. He lifts the man out of the coffin without any real effort and addresses the man. The large being doesn't speak. Instead there's a voice inside the man's head.
The being lectures the man, explaining a journey that the little people are making. The being also explains that the little people must die.
The being, who calls himself an elder god, doesn't appear to the man as a larger, nobler version of the little people, as one might think. The being appears to the man as a large biped with horns on his head and a long tail ending in an arrow point.
