Get a small dome tent. They are very light, easy to set up. They have a floor, The keep the rain and wind out. To make things comfortable to sleep on, use a lot of leaves on the tent floor where you are going to bed down. Clean up is easy. Take the tent down and turn it inside out and brush off. Then turn tent back to original, fold, and put back into its carrying case. Devout backpackers have been using these things for decades.
No such thing as a stupid question. What is stupid is not asking it.
