Sleep in someone’s house demands a very high level of trust from both. Not in the sexual meaning of the word but, just sleeep in the same house or room with the other. By the fact that when you’re sleeping, you’re vulnerable to the other. While you’re asleep you can’t see or do nothing, so a bad intentioned person can harm you. Any person that you share the room could be a potential risk. Independent who is, your friend, brother anyone you give a great power by sleeping next to him. So, if someone invites you to sleep at his house either this person is crazy or he has a high level trust in you, wich means that your relationship with this person are having great progress. But if you invite another person to sleep at your home is a higher level of trust, ‘cus this person accepted to sleep in a foreign territory and as this territory are not known makes him more vulnerable, wich implies more trust in you. Anyway if someone come to the point to show you his weakest moment, be proud of it cus this person has a really especial bond with you. Agree?📷📷📷
