LAYING vs LYING down? And getting vs having or taking a shower?

[AbsentmindedWoman]

I have noticed that 'laying' seems to have replaced 'lying', in a lot of instances, has anyone else noticed this too?

And curiously I think lots more people refer to 'getting a shower' rather than 'having a shower'. Or taking.

To clarify, it doesn't make me angry or anything I'm just wondering if language is shifting.

Currently laying/ lying on my sofa feeling like I've been dug up recovering from a really bad diabetic hypo which always makes me ponder stuff like this.

I remember the following from school.

Pupil. Please miss can I go to the toilet.
Teacher Can you? I don’t know, but you may go and try if you wish.

Lie is correct to me but I don't get too upset about lay.

I'd say going in the shower, all of those others sound twee to me.

I have noticed to too and I hate it!
