Spirit Places
Physical places have a coexisting spirit "place" in the spirit dimension. The physical environment and furnishings reflect something of the spirit environment and "furnishings". The focus here is how the environment affects you so you can choose to avoid a sin/evil provoking environment. There are times (under God's leadership) to enter evil environments with the things and Person of God.
There is also a spirit "place" where out spirits can go without "out of body" travel or visiting physical lairs. We can mentally and spiritually hang out with spirits through music, meditation, and sharing thoughts and emotions with them. Our stay with them will affect out mind, decisions, and heart. Pornography and its effects are a very good example of this process.
With good reason, the Bible says to bring every thought under control. Be careful, watch out.
