Spiritual Journey.

So I won't go into much detail about why this happened, but my brother law was belligerently drunk last night and walked into the woods angry at his wife. She called us and asked us to come over to help. When we got over there he had walked out of the woods and was crying on the ground. My wife went and talked to him. He told her he walked about a mile and a half into the woods when he started seeing black masses that were moving. And he heard someone or something scream. He then heard something tell him to turn around and go back. While he was on his way back he talked to this thing and it told him to change his ways and to love his wife and kids. He said that this thing wasn't mean. But it didn't speak in a dialect that he was familiar with but he understood what it was saying. He told me when he got out of the woods that it scared him so bad he will never go back in the woods again.

What do you think this thing could have been? He may have been drunk but he was still coherent and able to function. So I don't think it was the alcohol that gave him this revelation in the woods.
