The thoughts I got when I read them are as follows:

Dream 1~
First you are in a place of safety, comfort and love...your childhood home, represents our Heavenly home, since as children, we equate our parents as the ultimate protectors/caregivers, basically, as our image of 'God'. Expecting the arrival of your late father is another way to say you are expecting Jesus. You are toiling to 'be ready'...the work is hard and plentiful, much to do. You 'finish', only to discover there is still more to be done. Our work is really never done to prepare for His arrival. The grass will continue to grow, and we can only do as much as is physically/spiritually/emotionally possible as the imperfect humans we are. But doing it 'for the Lord' is what counts. Keeping our eyes on 'being ready', and not giving up/stopping is what matters.

Dream 2~
This represents the 'temporary home' we have here on earth. They are familiar and comfortable places, but not our 'permanent homes'. You are worried about your family, feel the need to prepare them, make them ready to meet any danger/storm that is coming. You KNOW it is coming, you can see/feel it. You cannot reach your child, at that age, only God can...but that's okay, you have set the foundation, now it is up to him to accept Christ in his own right. The nephew (you didn't state age), sounds like one who is at the age of accountability, and there again, must make that decision on his own. He may think he 'has time', but you know that time is indeed short. Share your dream with him and let him know that he can't dilly dally...when God comes, and the destruction that follows, he will not have time to dawdle. Your mother is fine. She is the only one in the dream who is completely READY to go. I love it. The one who this world sees as 'out of it', is the one most in touch with our Lord. Glory!

Dream 3~
A very helpless dream...you know she KNOWS the truth, but her 'maturity' in the ways of the world is clouding her judgment. Keep praying for her.

All the dreams are pretty much the same. You know time is short. You know we must all be ready. You are afraid that some of your loved one's aren't prepared 'to go'. You are worrying that you have not 'reached' your own child, but I don't think you have to worry about him. The nephew, pray on him, and talk to him....he can't call the shots, it's not on HIS time, it's the Lord's time when things will go down. We are not guaranteed a number of days on this earth, the warning signs are here now, he must prepare his heart NOW.
Do not worry about your mom, *I can't help but smile when I picture her all dressed in her Sunday Best, waiting on Him*...she's better off that many others. Praise Him. Also, for yourself, you can only do so much to 'be ready'. Half of what you do is of your own actions...the rest is up to God. Don't fret, it's what is in your heart, not your deeds and actions that He will see. Unfortunately, there will always be some things left 'undone' when the time arrives.

I am not claiming this is an interpretation from the Lord, I've just always been able to understand the symbols our mind uses in dreams. These are very common thoughts we all go through, so it's not so 'out there' to figure that is what is in your mind and your subconscious is playing it out in dream form. The best thing you can do is pray that everyone you love is ready. This world is just a temporary place for us, we can enjoy the gifts God has given us in our time here, but know that our real place and treasures are yet to come.

Blessings~
