Which state ????: This is typical of a BLISTER BUG. They are common in Texas and south-west USA., also south-central USA. If you live in the northeast or west coast, it is something else. The insect tickles when it craws on you during your sleep, you brush it aside, and it secretes cantheradan which is a defensive adaptation. Cantheradan is a potent vesicant. If that is the case, wash gently. Cool water will be soo
