Ever get that feeling like you’ve done this before? Like all of a sudden you remember doing this exact thing and saying this exact thing in this exact place? But you couldn’t have, right? Remember our conversation from last week: Time travel only exists in books—for now.

So, where does that feeling come from?

Déjà vu is French for “already seen.” An article from Psychology Today explains déjà vu in this way:

Psychologists who study memory point out that we have memories for things that have happened to us, and also memory for where we encountered the things that happened to us. That memory for where we encountered information is called source memory.

There are two ways that you can recognize that you are in a familiar situation:

One is to retrieve the previous situation from memory. For example, you might visit the town you grew up in. When you go to an old school you went to, you might remember a class you took and know that you had been there before.

But, you can also just get a feeling that you have been somewhere before. This feeling of knowing is related to knowledge about the source of a memory. So, when visiting the town where you grew up, you might pass the library and feel that it is familiar without remembering ever going there.

The experience of déjà vu involves having that feeling of knowing in a situation in which you are experiencing something totally new.

I’ve had this experience more times than I can count in my life. Each time, I find it both fascinating and unsettling. (Time travel still doesn’t exist, right?)

Okay, so now that we’ve had our “learn something new” experience for the day, imagine that instead of déjà vu, you experience the opposite. You see something that can’t possibly be true and yet there you are, looking at a photograph of yourself taken in a time and place you know you’ve never been. This isn’t déjà vu. This is impossible.

Unless, of course, you’re a character in Dean Wesley Smith’s Thunder Mountain series. In that case, you’d better buckle up and hang on because you’re in for one hell of a ride.

Our latest release in Dean Wesley Smith’s Thunder Mountain series, Lake Roosevelt, adds rich dimension to the complex world Dean has been building into this series.

Here’s the synopsis:

In a small diner on the Oregon Coast, Kelli Rae meets a handsome man named Jesse Parks. Turns out she had seen him in a picture taken in an old mining town in Idaho over a hundred years before.

And even worse, he had been following her.

A time-travel adventure in the popular Thunder Mountain series that promises to change everything about the series.

If you haven’t read this series yet, you should give it a try. You can enter the series at any point, as the novels all stand alone, although I do recommend going back to Thunder Mountain and starting there. And don’t forget that the fourth book in the series, The Edwards Mansion, is available in the Time Travel StoryBundle for a limited time.

Wait, in this new world of publishing, you can go back in time and start a new series no matter how long it’s been in print? Yup. But I feel like I’ve told y’all that before.

Must just be déjà vu.
