You do need to visit the emergency room. Just move on from this, and don't fall into the trap that everybody does on this website. Don't obsess over this. It could either be a week long affair that you can easily move past and not worry about, or you can turn it into months of obsessing over what happened, and convincing yourself that you still feel funny. There are people who train the minds to have DP for years. You get out of this by moving on and not fretting. As for the smoking before bed, it all depends on how well you handle the effects of marijuana. I know that when I'm super stressed, weed gives me anxiety, but I can also have great experiences. I'm really sorry about your life circumstances. These are all things that are so extremely difficult in them midst of them, but from the many situations involving custody of children, and divorces, things usually settle down and compromises are made so people can move on with their lives. My parents divorced a year ago, and it took them a year to figure out how to make everyone happy, but they figure it out. Find somebody you can lean on, a friend or family member who you can talk with to make the situation a little less lonely. Sometimes you need to get real sad to feel real happy again. So this dream mode will go away if you just live with it for now and trust that it will go away in time. If you worry and obsess about it, it will stay with you.
