Congrats HanZartaC on what sounded like a very nice lucid dream!!

I'm weirded out, I have no idea why I wouldn't wear shirts in my dreams. I don't know, maybe another dream sign?
Missing clothes is a common dream theme/sign. You could definitely use it as a dream sign if you don't normally walk around shirtless in a particular scenario.

Have you ever felt like your senses were heightened in a dream?
Absolutely! You may also notice heightened senses in waking life.

Did you say you had some tweaks to it?
Only if you are remembering so much that you find it tiring. Is that the case?

Do you have any other advice on dream recall?
Recite a mantra before bed that when you feel yourself back in bed (waking up) that you will lay still, keeping your eyes closed. When you wake you will ask yourself "What was I just dreaming?"

And do you recommend waking up after every dream (with an alarm, I'm a deep sleeper) to try to remember my dream?
Not after every dream by alarm. Drink a lot of water before bed which will wake you up more gently. Resist the urge to jump up straight to the bathroom and use the mantra/plan above when you do wake needing to go to the bathroom.

And also, do you have any ideas/advice on my "plan" above?
Which part?

Again, congrats on your LD!! Ride that exhilaration to continue your progress! To further success!
