Well, daydreaming about it yes, but I am talking about dreaming about this while asleep, so far my brain hasn't done that, but fortunately it has happened to other people. I do wish good dreams like that on people who want them, there are lots of other good dreams we can have too, such as being on the beach under a hot summer's sun, and in dreams we can transcend our bodily limitations, like if we are old with arthritis hurting our joints, being in a dream while asleep, it is possible to dream about being young again and not having arthritis, in some cases people dream about flying, too, or falling in a nightmare as the case may be although nobody wants that.
That is so cool that you had a dream about Applejack a long time ago, where did you meet in that dream? Everfree Forest? her home at Sweet Apple Acres? Ponyville? or badlands? what I'd give to actually talk to her, I don't care about material possessions, having the basics would be fine because friendship in a fictional place like Equestria would be a powerful antidote to a bad mood and stress. Having friends to share happiness with in a peaceful place, it would feel like Heaven.
