I agree completely with House. These feelings are most likely coming from the fact that you do not feel safe in your own home. I know I wouldn't feel safe in my own home after something like that happening. A burglary can be a very traumatic experience.
I would suggest taking a break from doing it at home. Maybe go to a like minded friends place to explore these worlds, then you can have someone there to talk you through it as well if needed. A nice quiet, secluded spot in nature is also a good suggestion as House stated above. If you choose to do so out in nature, bring someone with you. I dont know about you, but I dont think I would feel comfortable being out in nature tripping that hard without someone there to make sure nothing bad happens.
Try looking into some security systems for your house to ease your mind regarding the burglary thing. Maybe this will allow you to feel safer and more secure for venturing in your own home. I hope you can find a way around this and feel safe in your own home again.
Everything published by Gone-and-Back are the mad rantings and ravings of a mind who yearns to be free and thinks he knows what he is talking about. However, these are just delusions made to feel that freedom, because that freedom will never come. Any experiments done are purely figments of the imagination, and are falsified to the highest degree. Nothing should be taken seriously from a crazy mans mind.
