I apologize you had such a long wait for an answer. I would like to help.
Do you have anyone close to you who has past away?
Do any of those colors or textures signify anything to you?
I am so sorry about what happened. You have been through a lot. I can imagine how much this took out of you. It is not easy at all and I believe your dream is an expression of your subconscious. Your feelings for your loved ones are also within you and I think this dream was an expression of your subconscious reminding you that they are still with you and watching over you. Even though they have left physically they are still with you spiritually and emotionally. And one day you will see them all again. Our dreams have strange ways of expressing things and the colors and textures may be related in a direct way that you may not realize right now or it can be a symbol of something else that mixed itself with these other feelings while you were asleep.
I am so sorry about you losing all these family members and the way it way it all happened. God bless your heart.
