Your personality sounds similar to mine, so even though your friend obviously knows you better than I do I'd like to share my experience with magic mushrooms since I really enjoyed them:

At any dosage short of over-the-top heroic doses I never experienced any real feelings of loss of control (full disorientation or ego loss), and no true visual hallucinations either (plenty of visual distortions like surfaces "breathing" and shining/sparkling, but no seeing objects that aren't there).

Low/medium doses of shrooms were actually very similar to strong weed edibles for me, in that there's an intense body high and very minor visual glitches, but I never felt lost or confused like you do with acid or other hallucinogens.

I don't have access to them anymore, but personally I'd consider any kind of comfortable couchlock-friendly environment a good setting to experiment with shrooms. Going out in nature can be incredible if you've got a safe outdoors environment close to your couchlock homebase, but it's not required to have a great time. Any chilled out activity in a cozy place that would be fun on weed edibles would also be a fine candidate for a shroom trip.
