Based on gardening and based on smudging.
Although sage contains many nutrients, and medicinal properties, burning and inhaling these will potentially negate any positive effects they might have, so it isn't really recommended to burn them in closed spaces.
Eating, or using infusions, as well as using sage oils in a vaporizer for your room can be a healthy option to get the effects of Sage's medicinal properties.

I bought common sage seeds but these don't look like them as they do not have the characteristic fuzzy leaves. I'm trying to determine if they're something different.
I'm not able to identify this plant, though it is not Sage.
This article shows what common Sage should look like.

As of a month ago both my California sage brush lost its leaves completely. Looks dead. I cracked a thick piece and saw it's still green on the inside Woody part. So I'm feeling like it's probably alive. But I don't know for certain. I get like it got too much water and maybe caused them to go deciduous.
It sounds like too much water. These are well suited for dryer climates, so any soil saturation for too long will lead to rot and dormancy in attempt to preserve itself.
Unfortunately, your photo did not come through, so I cannot assess the damage, but correcting watering habits and treating with a fungicide will help it to recover.
Since I do not know if you are referring to Artemesia or Salvia, which are both commonly called sages (they have very similar care), but I'll include some of our articles for both:

I have a Texas Sage tree (2 years old) (can I bring it into my 3 season porch in the pot (can get down to 35 degrees & has plastic all around the porch so NO wind or snow on it) & expect it to winter over for me?
It doesn't sound like your porch will stay warm enough for the sage. One unexpected freezing spell could do it in. Here's an article with info about how to get it through the winter: https://www.gardeningknowhow.com/edible/herbs/sage/growing-sage-plant-indoors.htm
Had a hard freeze early October and the sage froze. When should I cut it back and how far?
If you want to tidy up, this article says they can be cut back to a foot above the ground. You should definitely mulch them for the winter. Or you can just wait till spring and cut them back to the first set of leaves.

I have a sage plant in my garden that is 3 years old. This spring I noticed that the leaves have changed. The original leaves were narrow and pointed, like the sage you see in supermarkets. The new leaves are still pointed but wider at the base, almost heart-shaped, and they are not fuzzy like the old ones. I am not sure what happened. Any ideas?
Perhaps by now the leaves are larger and now looking more like last year's. This article may help:

I just noticed this today on my sage plant. I’m not sure if it’s good or not?
It's a nest of baby spiders, so great for the garden. You might find if you touch it they all scatter and then return to the nest - video it it's magic!
