Sometimes details in dreams can be clues, objects or conditions and your associations to them. Without that, one thing I might wonder is whether there were some unfinished business between you and this person, especially where you may feel you let them down or didn’t hear them or let them in in some way. In dreams a house can mean yourself, or your life. I don’t see closing them out as your desire, but as a symbol of guilt or anxiety you may be carrying. Your dream suggests you were not closing them out by choice, but in your lacking awareness to them, not seeing who they really are, or not hearing something they we’re trying to tell you. You may have missed something in your relationship with this person that you now wish you had been more open to or more aware of. If so, perhaps let them know in prayer and maybe you can share your love or support or awareness now.
