It has a feel that it's getting smaller or something.
It looks like the container is too large, thus holding excess water in the soil which could be damaging the roots. I would repot it into a smaller pot and be sure the soil dries out between waterings. Here are two articles that should help:

These are two houseplants but I don't know what they are called.
Those are in the dracaena family.

This plant was at the patio and I think it was frozen. Please tell me if I can still save it. Now it is indoor and drained all water . The leaves are dropped. I upload picture but cannot see it. Wonder if you can see it
You can resume its regular watering schedule and give it a boost of fertilizer to help it. I would also remove the damaged leaves. Hopefully only the leaves were affected and will grow back. Here is more:
2 years old planted in garden growing well, last year something grew out of it, this year have 2 sprouting looks like corn on cob seeds what is it?
It's just a bloom spike. Did you let it bloom? After it blooms, cut off the spike at the base.
In a nutshell I'd like to ask about pruning and regrowing canes still on the plant. 1. If the main stem already has three vertical shoots growing out of it all with a full canopy, if you cut off the heads of those three, will the sub canes grow new sprouts or does it only work on the main stem? 2. Same concept if you only prune one of the sub canes because its uneven with the others will it grow it's own sub canes or does the whole plant need to be headless to regrow?
You can lop off the whole top but be sure some nodes are included. Or you can just cut back one of the stems. They should all branch.

I have an 18" tall palm that is thriving, but the "trunk" is about as skinny as a toothpick and the base from where the leaves started growing is about 2" in diameter. What can I do to save this before it inevitably snaps off?
This is a tricky situation. That root should have been planted under the soil line when it was younger. With that being said, I would recommend a larger container. This way you can, carefully, plant up to that level. Just watch your watering after, since there will be quite a bit of soil with no roots in it.
house. The first plant, the one outdoors is a night-blooming Cereus, I have had about 10 years. It stays outside in the summer. The second one I don't know what it is, I bought it at Ikea and have had it almost 30 years. Can you tell me how to safely prune them, I don't want to harm them but they are becoming too big for the house.
Prune, no more, than 1/3 of each plant at one time. With the Dracaena, cut back to your desired height. Preferably, one branch per week. This should be done during the active growing phase, which can be just about any time indoors.

The Night Blooming Cereus will prefer a summer pruning, as well, during the active growing season. They are, not at all, picky about pruning, but it is always best to follow the "1/3" rule.
