In what seemed to be your house with family I believe represents your church family. (Or body of Christ as a whole) It appears that you want to tidy up your spiritual walk and move on from just “camping” or possibly moving from church to church, or house to house. The tree branch that is more like a leach that needs to be severed (the knife indicates cutting away by the Word of God) could represent a person or particular group of people who influence the body of Christ in a negative way. This is also true of your Father in law, smoking a cigar. My experience with father in law in dreams is that of influence that is not of the Holy Spirit but more so the law or traditions of men. (Trying to please people more than Christ) The law competes with Jesus instead of embracing Him as Lord. So, the land Lord, I believe represents Jesus or someone He has in a position of true authority over you that wants to help you make a distinction between the two by putting up a door of security between the bedroom, inner chamber (your inner thoughts and what you really believe) and the rest of the house. Everything flows from our Spirit through the soul and then to the body in a natural sense. What I see about Rev 3 is that God will open doors that no man can shut and shut doors that no man can open for you. I know He promised that to me when I was making this type of transition from a legalistic institutionalization of church performance, to finding my place of security in Christ.
