I'll give you an example of my imaginary game (it's a little bit different than plain imagination, Ven

):
Okay, so there's a world map in my bedroom because I adore travelling, countries, populations and cities around the world etc.
If you point to any city or location on that map, I could tell you what it was almost instantly, and there are thousands of names on there.
This is because I read them to myself every day. I usually listen to a song which begins with the same letter as them on a random playlist and just memorise them. I'm like a human GPS unit when it comes to travelling- in fact I'm probably more reliable. Give me a map and you will NEVER get lost. I can stand in my room for hours doing that too, and I would never get bored. It's like...a part of my life now, a very big part.
I dunno about others here but I used to hold up my hands if I was concentrating on something. It was instinct, like, I couldn't not do it. The kids used to make fun of me because of it.. ._.
Also with autism I think it's rather rare that you have to take meds for it @Ven. Though I know fully how you feel with that whole idea in general. Only difference for me is I was diagnosed officially when I was 5 and my parents suspected it when I was 3. :3 And lucid dreaming is awesome, I'm not a natural lucid dreamer, but I have trained myself to get them. I am a regular dreamer in general though- I dream every single night and I realised that when I was keeping a dream diary.
