Can copinglinkers ‘make’ themselves feel astral limbs? Is this unhealthy?

The human mind can construct all sorts of experiences with practice. Its very likely that at least some copinglinkers could construct the experience of astral limbs. Though I’m not sure if the feeling would be ‘the same’ as someone who experiences them naturally would have them. I have no evidence it would be any different, either. We’d have to get brain scans and seeing what parts of the brain light up for each in order to determine that.
