I wouldn't be at all surprised if Rascal visits again, including in dreams -- dream-visit ADCs tend to be unusually vivid dreams you don't forget -- but it's impossible to predict or guarantee. I hope she will.
Your girls are likely to have such experiences, too, and that's one reason I suggested you tell them what you experienced, since often people are reluctant to mention their experiences, and when they finally do they find out they've happened to other people as well. (I remember being reluctant to mention this sort of thing to a neighbor who'd lost her husband and then their little dog in the year before I first brought this up to her, but as soon as I asked her if she'd ever dreamed of her husband, she smiled and said, "You might think I'm crazy, but I think he's been coming back..." and she told me of waking more than once to find that the kitchen light was on and there were noises from the kitchen, as when he'd be up in the middle of the night to get a snack, though the light she saw in the hall would be off again by the time she reached the kitchen. An aunt of mine has had similar experiences since losing her husband. That neighbor has also felt the dog jump on her bed and settle down to sleep on the pillow beside hers. It turned out her grown daughter had also been getting visits, but for months neither the widow nor her daughter spoke of them, until finally her daughter brought them up, which was good, since it comforted them even more to know what the other was experiencing.)
My best guess would be that Rascal was particularly eager to comfort you, partly as a way of thanking you for trying so hard to save her, and she wanted to make sure you knew she was all right now.
I believe our loved ones on the other side always want to comfort us, but people seem to vary a lot in how aware they are of such attempts (how psychic or intuitive they are), and they often tend to brush aside such experiences (partly because they're worried other people will think it's delusional). And I think some spirits are a bit better than others at communicating.
Children, especially very young children, seem to be more open to such experiences. Their brains tend to produce a lot of theta waves, just as animals' brains do, and it often seems that both kids and animals are more aware of spirits, and visits. I know people who've lost pets whose children have a lot more visits from the pet than the parent does (I'd better rephrase that -- I don't think they're actually being visited more; they're just more aware of the visits). In one case a woman was startled to discover her youngest daughter had seen the dog they'd lost with the different coloring she'd had when very young, before her daughter was born, coloring her daughter wasn't at all familiar with.
But adults can regain some of that ability if they meditate a lot, since that will make your brain produce more theta waves, and people who have meditated a lot, any type of meditation, seem to have more ADCs.
The brain also tends to produce more theta waves when you're in that twilight state between waking and sleeping, and that's when these experiences are more likely to happen, too. (This is also a very creative time, when the solutions to problems are more likely to come to you.)
You don't have to be naturally psychic or an experienced meditator or even really open to these experiences to have them, though. And I especially love it when someone I meet who'd previously been very skeptical of them has an ADC that's so clear it's pretty much impossible to continue doubting.
It's wonderful when people admit to those experiences, too, since so often people will keep any ADC experiences to themselves that most people don't realize how common they are. I've read about surveys showing that quite a few people have had them, and it's an especially high percentage for people who've lost a spouse (like my widowed aunt, and that neighbor of mine; and in my aunt's case, her grown son, who lives with her to help take care of her, has also heard and seen things that convince him that his dad is visiting).
ADCs tend to be more common on significant dates, too, such as the anniversary of a death, or your loved one's birthday or your own. And they tend to be more common when someone is stressed and in more need of comfort.
I wish everyone had these experiences, and from every loved one they lose. But grief can often block them, just when you need them most, and any kind of stress can block them, probably because it makes that type of brain wave pattern less likely. ADC experiences are also less likely for people who are on drugs that affect the brain (they've done studies of dying patients who reported being visited by loved ones on the other side before they crossed over themselves, and they found that it was the people who weren't drugged as much, who were more lucid, who had more such experiences; again, this was probably because of the drug's effect on brain wave patterns).
Dr. Melvin Morse's books, as I said last night, are particularly interesting. He started out very skeptical of near death experiences, but the more he studied the experiences his young patients had, the more convincing he found them, and he also learned more about ADCs in general. He has a websitehttp://www.melvinmorse.com/
which has some very interesting articles, too, especially here:http://www.melvinmorse.com/light.htm
Whoops, that's also the index page, which is apparently a frame for every page there after the first one. Here's a direct link to that page, the Downloads page you'll find a link for on the left side of the frame:http://www.melvinmorse.com/trans.htm
